9e3c94d117 env/sf.c: drop private CMD_SAVEENV logic
Deciding whether to compile the env_sf_save() function based solely on
CONFIG_SPL_BUILD is wrong: For U-Boot proper, it leads to a build
warning in case CONFIG_CMD_SAVEENV=n (because the env_save_ptr() macro
causes the function to indeed not be referenced anywhere). And for
SPL, when one selects CONFIG_SPL_SAVEENV, one obviously expects to
actually be able to save the environment.

1df96a7e76 env/ext4.c: remove CONFIG_CMD_SAVEENV ifdef
Removing this ifdef/endif pair yields a "defined but unused warning"
for CONFIG_CMD_SAVEENV=n, but that vanishes if we use the ENV_SAVE_PTR
macro instead. This gives slightly better compile testing, and
moreover, it's possible to have

  CONFIG_CMD_SAVEENV=n
  CONFIG_SPL_SAVEENV=y
  SPL_ENV_IS_IN_EXT4=y

in which case env_ext4_save would erroneously not be compiled in.

1d0adee45c env: add SAVEENV as an alias of the CMD_SAVEENV symbol
Currently, testing whether to compile in support for saving the
environment is a bit awkward when one needs to take SPL_SAVEENV into
account, and quite a few storage drivers currently do not honour
SPL_SAVEENV.

To make it a bit easier to decide whether environment saving should be
enabled, introduce SAVEENV as an alias for the CMD_SAVEENV
symbol. Then one can simply use

  CONFIG_IS_ENABLED(SAVEENV)

080019b86c make env_entry::callback conditional on !CONFIG_SPL_BUILD
The callback member of struct env_entry is always NULL for an SPL
build. Removing it thus saves a bit of run-time memory in the
SPL (when CONFIG_SPL_ENV_SUPPORT=y) since struct env_entry is embedded
in struct env_entry_node - i.e. about 2KB for the normal case of
512+change hash table entries.

Two small fixups are needed for this, all other references to the
callback member are already under !CONFIG_SPL_BUILD: Don't initialize
.callback in set_flags() - hsearch_r doesn't use that value
anyway. And make env_callback_init() initialize ->callback to NULL for
a new entry instead of relying on an unused or deleted entry having
NULL in ->callback.

e13df08a26 env: remove callback.o for an SPL build
env.h says this about about callback declarations (U_BOOT_ENV_CALLBACK):

 * For SPL these are silently dropped to reduce code size, since environment
 * callbacks are not supported with SPL.

So env_callback_init() does a lot of work to not find anything in the
guaranteed empty env_clbk list. Drop callback.o entirely from the link
and stub out the only public function defined in callback.o. This cuts
about 600 bytes from the SPL on my ppc build.

46d9d1c306 env: make file-scope env_ptr variables static
The combination ENV_IS_IN_NVRAM=y, ENV_IS_IN_REMOTE=y fails to build:

env/remote.o:/mnt/ext4/devel/u-boot/env/remote.c:17: multiple definition of `env_ptr'
env/nvram.o:/mnt/ext4/devel/u-boot/env/nvram.c:41: first defined here

It's not necessarily a meaningful combination, but for build-testing
it's nice to be able to enable most ENV_IS_IN_* at the same time, and
since these env_ptr are not declared anywhere, they really have no
reason to have external linkage.

nand.c and flash.c similarly already define file-scope static env_ptr
variables.

c82216803d env: another attempt at fixing SPL build failures
I'm also seeing the build failure that commit

7d4776545b env: solve compilation error in SPL

tried to fix, namely that the reference to env_flags_validate from
env_htab cannot be satisfied when flags.o is not built in. However,
that commit got reverted by

d90fc9c3de Revert "env: solve compilation error in SPL"

Necessary, but not sufficient conditions to see this are

CONFIG_SPL=y (obviously)
CONFIG_SPL_ENV_SUPPORT=n (so flags.o does not get compiled)
CONFIG_SPL_LIBCOMMON_SUPPORT=y (so env/built-in.o is part of the SPL link)

Now, these are satisfied for e.g. imx6q_logic_defconfig. But that
builds just fine, and spl/u-boot-spl.map lists .data.env_htab among
the discarded (garbage collected) sections. Yet, on our
mpc8309-derived board, we do see the build failure, so perhaps the
linker works a bit differently on ppc than on ARM, or there's yet some
other configuration option needed to observe the break.

This is another attempt at solving it, which also cleans up
env/Makefile a bit: Introduce a def_bool y symbol CONFIG_ENV_SUPPORT
which complements CONFIG_(SPL/TPL)_SUPPORT. Then use
CONFIG_$(SPL_TPL_)ENV_SUPPORT to decide whether to include the five
basic env/*.o files. For attr.o, flags.o and callback.o, this
shouldn't change anything. Also, common.o and env.o still get
unconditionally built for U-boot proper. But for TPL/SPL, those two
are only included if CONFIG_(SPL/TPL)_SUPPORT is set.

Having that symbol should also allow simplifying conditionals such as

#if !defined(CONFIG_SPL_BUILD) || CONFIG_IS_ENABLED(ENV_SUPPORT)

found in drivers/reset/reset-socfpga.c to just
CONFIG_IS_ENABLED(ENV_SUPPORT).

- Add ENV_xxx_REDUND options that depend on their primary option and
  SYS_REDUNDAND_ENVIRONMENT
- On a number of PowerPC platforms, use SPL_ENV_ADDR not CONFIG_ENV_ADDR
  for the pre-main-U-Boot environment location.
- On ENV_IS_IN_SPI_FLASH, check not for CONFIG_ENV_ADDR being set but
  rather it being non-zero, as it will now be zero by default.
- Rework the env_offset absolute in env/embedded.o to not use
  CONFIG_ENV_OFFSET as it was the only use of ENV_OFFSET within
  ENV_IS_IN_FLASH.
- Migrate all platforms.

We have CONFIG_ENV_SIZE_IS_REDUND but don't really use it.  We have one
board where we can simply multiple CONFIG_ENV_SIZE by two for the same

this is for where env_internal.h checks for if we should set
ENV_IS_EMBEDDED.  This seems like the most likely use, historically, of
the variable, but it was not used.  Add logic to check for this now.

6116234174 ubi: env: fix redundand management
We check (with a #if defined()) the config ENV_UBI_VOLUME_REDUND
to know if there is a redundant env. But this config is a string
and is always defined with env is in ubi, so we always consider
that a redundand env is used.

To fix this issue, I've added a hidden flag ENV_UBI_IS_VOLUME_REDUND
that is true when ENV_UBI_VOLUME_REDUND is not "". Then, I check
this flag in the code, instead of the string ENV_UBI_VOLUME_REDUND.

f2fae512f2 env: Don't check CONFIG_ENV_OFFSET_REDUND for SPL build
When booting using an SPL on am335x, if we want to support booting with
the boot ROM loader via USB (which uses RNDIS, making bootp and tftp
calls) we need to enable gadget eth in the SPL to load the main U-Boot
image. To enable CONFIG_SPL_ETH_SUPPORT, we must enable
CONFIG_SPL_ENV_SUPPORT as the environment is used by the eth support, but
we don't actually need to have environment variables saved in the SPL
environment. We do however have environment variables saved in the main
U-Boot image and enable CONFIG_ENV_OFFSET_REDUND (we are storing in raw
NAND). In such instances, even with the build config enabling both
CONFIG_CMD_SAVEENV and CONFIG_CMD_NAND, these options aren't set when
building the SPL, but CONFIG_ENV_OFFSET_REDUND still is.

Don't check this configuration option for SPL builds to enable the above
configuration.

5efc0686ee fs: ext4: Add support for the creation of symbolic links
Re-use the functions used to write/create a file, to support creation of a
symbolic link.
The difference with a regular file are small:
- The inode mode is flagged with S_IFLNK instead of S_IFREG
- The ext2_dirent's filetype is FILETYPE_SYMLINK instead of FILETYPE_REG
- Instead of storing the content of a file in allocated blocks, the path
to the target is stored. And if the target's path is short enough, no block
is allocated and the target's path is stored in ext2_inode.b.symlink

As with regulars files, if a file/symlink with the same name exits, it is
unlinked first and then re-created.

This reverts commit 9a9d66f5ef.

because it breaks fw_setenv and U-Boot interworking, if
U-Boot environment is stored in a SPI-NOR.

Reproduce it with:
boot linux with empty Environment and store a variable
with fw_setenv into it, the Environment is now filled
with 0xff:

root@ckey5e:10:8e:~# hexdump -C /dev/mtd4

00000f40  00 ff ff ff ff ff ff ff  ff ff ff ff ff ff ff ff  |................|

Boot now U-Boot prints:

Loading Environment from SPI Flash... SF: Detected s25fl128l with page size 256 Bytes, erase size 4 KiB, total 16 MiB
*** Warning - bad CRC, using default environment

Reason is the above commit, as it only reads until \0\0
is found, and assumes the rest of the Environment
space is filled with 0x00, which is not the case when
saving an Environment under linux with fw_setenv.

293a172b67 env: Fix saving environment to "bad CRC" location
In case when the environment on some location is malformed (CRC isn't
matching), there is a chance we won't be able to save the environment to
that location. For example, consider the case when we only have the
environment on eMMC, but it's zeroed out. In that case, we won't be able
to "env save" to it, because of "bad CRC" error. That's happening
because in env_load() function we consider malformed environment as
incorrect one, and  defaulting to the location with highest (0)
priority, which can be different from one we are dealing with right now
(e.g., highest priority can be ENV_FAT on SD card, which is not
inserted, but we want to use ENV_MMC on eMMC, where we were booted
from).

This issue began to reproduce after commit d30ba2315a ("u-boot: remove
driver lookup loop from env_save()") on BeagleBone Black, but that
commit didn't introduce the wrong logic, it just changed the behavior
for default location to use, merely revealing this issue.

To fix that, let's implement next logic in env_load():
  1. Try to find out correct environment; if found -- use it
  2. If working environment wasn't found, but we found malformed one
     (with bad CRC), let's use it for further "env save". But make sure
     to use malformed environment location with highest priority.
  3. If neither correct nor malformed environment was found, let's
     default to environment location with highest priority (0)

Steps to reproduce mentioned issue on BeagleBone Black (fixed in this
patch):

1. Boot from SD card and erase eMMC in U-Boot shell:
   => mmc dev 1
   => mmc erase 0 100000
   => gpt write mmc 1 $partitions
2. Write new SPL and U-Boot to eMMC; the rest of eMMC will stay filled
   with zeroes
3. Boot from eMMC; try to do:
   => env save
4. Observe the error (incorrect behavior). Correct behavior: environment
   should be stored correctly on eMMC, in spite of it has "bad CRC"

49d04c589c env: common: Return specific error code on bad CRC
Callers of env_import*() functions might want to check the case when we
have incorrect environment (with bad CRC). For example, when environment
location is being defined in env_load(), call chain may look like this:

    env_load() -> drv->load() = env_mmc_load() -> env_import()

Return code will be passed from env_import() all way up to env_load().
Right now both env_mmc_load() and env_import() return -EIO error code,
so env_load() can't differentiate between two cases:
  1. Driver reports the error, because device is not accessible
  2. Device is actually accessible, but environment is broken

Let's return -ENOMSG in env_import(), so we can distinguish two cases
mentioned above. It will make it possible to continue working with "bad
CRC" environment (like doing "env save"), instead of considering it not
functional (implemented in subsequent patch).

9a9d66f5ef env: add spi_flash_read_env function
The spi_flash_read_env function is a wrapper over spi_flash_read, which
enables the env to read multiple flash page size from flash until '\0\0'
is read or the end of env partition is reached. Instead of reading the
entire env size. When it reads '\0\0', it stops reading further the env
and assumes that the rest of env is '\0'.

This is an optimization for large environments that contain few bytes
environment variables. In this case it doesn't need to read the entire
environment and only few pages.

location list but it should save the environment into the location
stored in gd->env_load_location by the last env_load() call.

c5d548a9f8 env: common: accept flags on reset to default env
The function set_default_env() sets the hashtable flags for import_r().
Formally set_default_env() doesn't accept flags from its callers. In
practice the caller can (un)set the H_INTERACTIVE flag, but it has to be
done using the first character of the function's string argument. Other
flags like H_FORCE can't be set by the caller.

Change the function to accept flags argument. The benefits are:
1. The caller will have to explicitly set the H_INTERACTIVE flag,
   instead of un-setting it using a special char in a string.
2. Add the ability to propagate flags from the caller to himport(),
   especially the H_FORCE flag from do_env_default() in nvedit.c that
   currently gets ignored for "env default -a -f" commands.
3. Flags and messages will not be coupled together. A caller will be
   able to set flags without passing a string and vice versa.

Please note:
The propagation of H_FORCE from do_env_default() does not introduce any
functional changes, because currently himport_r() is set to destroy the
old environment regardless if H_FORCE flag is set or not. More changes
are needed to utilize the propagation of H_FORCE.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

f3d8f7dd73 Allow providing default environment from file
Modifying the default environment via CONFIG_EXTRA_ENV_SETTINGS is
somewhat inflexible, partly because the cpp language does not allow
appending to an existing macro. This prevents reuse of "environment
fragments" for different boards, which in turn makes maintaining that
environment consistently tedious and error-prone.

This implements a Kconfig option for allowing one to define the entire
default environment in an external file, which can then, for example, be
generated programmatically as part of a Yocto recipe, or simply be kept
in version control separately from the U-boot repository.

23ac79ff80 common: env_embedded: allow fine placement of environment object
Commit 7653942b10 ("common/env_embedded.c: drop support for
CONFIG_SYS_USE_PPCENV") dropped the .ppcenv section which was
used in linking scripts to allow fine placement of embedded
environment sections.

This implies that GCC randomly places objects from env/embedded.o
and environment is not guaranteed to be located at the correct address:

04003df8 g     F .text  00000038 mii_init
04004000 g     O .text  00000004 env_size
04004004 g     O .text  00002000 environment
04006004 g     F .text  00000040 .hidden __lshrdi3

This patch restores this capability by allocating each object marked
with __UBOOT_ENV_SECTION__ into a different section. Hence
'environment' will be alone in .text.environment, allowing a
fine placement in u-boot.lds with:

		. = DEFINED(env_offset) ? env_offset : .;
		env/embedded.o			(.text.environment)

901fb09d01 sunxi: disable direct MMC environment
Since the dawn of time for the Allwinner support in mainline U-Boot
we store the environment to the SD card and write directly at
544KB from the beginning of the device. This leads to problems when
the U-Boot proper image grows beyond 504KB and eventually overlaps.
With one release of having the environment preferably in a FAT
partition, let's now turn off the MMC variant fallback, so we get back
all the space we need to implement features.

Introduce another difference from upstream (kernel) source in
fs/ubifs/super.c: adding preprocessor condition as y variable in
mount_ubifs() depends on CONFIG_UBIFS_SILENCE_MSG:

Not setting CONFIG_UBIFS_SILENCE_MSG in am335x_igep003x_defconfig and

depends on CMD_UBIFS which is not set for them.

26862b4a40 env: mmc/fat/ext4: make sure that the MMC sub-system is initialized before using it
When booting from a non-MMC device, the MMC sub-system may not be
initialized when the environment is first accessed.
We need to make sure that the MMC sub-system is ready in even a non-MMC
boot case.

Therefore, initialize mmc before loading environment from it.

b2cdef4861 env: restore old env_get_char() behaviour
With multiple environments, the 'get_char' callback for env
drivers does not really make sense any more because it is
only supported by two drivers (eeprom and nvram).

To restore single character loading for these drivers,
override 'env_get_char_spec'.

e1caa5841e env: Fix env_load_location
Commit 7d714a24d7 ("env: Support multiple environments") added
static variable env_load_location. When saving environmental
variables, this variable is presumed to have the value set before.
In case the value was set before relocation and U-Boot runs from a
NOR flash, this variable wasn't writable. This causes failure when
saving the environment. To save this location, global data must be
used instead.

2166ebf783 env: make env drivers propagate env_import return value
For multiple env drivers to correctly implement fallback when
one environment fails to load (e.g. crc error), the return value
of env_import has to be propagated by all env driver's load
function.

Without this change, the first driver that succeeds to load an
environment with an invalid CRC return 0 (success) and no other
drivers are checked.

31f044bd91 env: move more common code to env_import_redund
There is more common code in mmc, nand and ubi env drivers that
can be shared by moving to env_import_redund.

For this, a status/error value whether the buffers were loaded
are passed as additional parameters to env_import_redund.
Ideally, these are already returned to the env driver by the
storage driver. This is the case for mmc, nand and ubi, so for
this change, code deduplicated.
