51bb33846a bootm: Support string substitution in bootargs
In some cases it is necessary to pass parameters to Linux so that it will
boot correctly. For example, the rootdev parameter is often used to
specify the root device. However the root device may change depending on
whence U-Boot loads the kernel. At present it is necessary to build up
the command line by adding device strings to it one by one.

It is often more convenient to provide a template for bootargs, with
U-Boot doing the substitution from other environment variables.

Add a way to substitute strings in the bootargs variable. This allows
things like "rootdev=${rootdev}" to be used in bootargs, with the
${rootdev} substitution providing the UUID of the root device.

For example, to substitute the GUID of the kernel partition:

  setenv bootargs "console=/dev/ttyS0 rootdev=${uuid}/PARTNROFF=1
		kern_guid=${uuid}"
  part uuid mmc 2:2 uuid
  bootm

This is particularly useful when the command line from another place. For
example, Chrome OS stores the command line next to the kernel itself. It
depends on the kernel version being used as well as the hardware features,
so it is extremely difficult to devise a U-Boot script that works on all
boards and kernel versions. With this feature, the command line can be
read from disk and used directly, with a few substitutions set up.

1a62d64c7d cli: Support macro processing with a fixed-size buffer
At present cli_simple_process_macros() requires that the caller provide
an output buffer that is exactly CONFIG_SYS_CBSIZE bytes in length. This
makes sense since it is designed to be used from the command line. But we
also want to use it for bootargs substitution.

Update the function to allow the caller to specify the buffer size. Also
return an error if the buffer is exhausted. The caller can ignore that if
preferred.

b6386f3841 bootm: Split out bootargs environment reading / writing
At present bootm_process_cmdline_env() reads the 'bootargs' variable and
then writes it back afterwards. This is painful for tests, which would
rather use a simple buffer.

It is also useful for zimage to use a buffer, since it does not actually
put the Linux command line in the bootargs variable.

Refactor the existing code into two pieces. One handles reading and
writing the environment variable, as well as allocating a buffer for use
by the rest of the code, which now operates on a buffer.

96434a76fd env: Allow returning errors from hdelete_r()
At present this function returns 1 on success and 0 on failure. But in
the latter case it provides no indication of what went wrong.

If an attempt is made to delete a non-existent variable, the caller may
want to ignore this error. This happens when setting a non-existent
variable to "", for example.

Update the function to return 0 on success and a useful error code on
failure. Add a function comment too.

Make sure that env_set() does not return an error if it is deleting a
variable that doesn't exist. We could update env_set() to return useful
error numbers also, but that is beyond the scope of this change.

8084e918bc armv8: layerscape: don't initialize GIC in SPL
The BL31 expects the GIC to be uninitialized. Thus, if we are loading
the BL31 by the SPL we must not initialize it. If u-boot is loaded by
the SPL directly, it will initialize the GIC again (in the same
lowlevel_init()).

This was tested on a custom board with SPL loading the BL31 and jumping
to u-boot as BL33 as well as loading u-boot directly by the SPL. In case
the ATF BL1/BL2 is used, this patch won't change anything, because no
SPL is used at all.

Hi,

This patch depend on the previous serie [1].

I don't test this patch on real hardware but
after this patch the size of the binary don't change.

In .config we have:
  CONFIG_ARCH_SUPPORT_PSCI=y
  CONFIG_ARMV7_PSCI=y
  # CONFIG_ARMV7_PSCI_1_0 is not set
  # CONFIG_ARMV7_PSCI_0_2 is not set
  CONFIG_ARMV7_PSCI_0_1=y
  CONFIG_ARMV7_PSCI_NR_CPUS=4

In u-boot.cfg, this patch only add the 2 lines
  #define CONFIG_ARCH_SUPPORT_PSCI 1
  #define CONFIG_ARMV7_PSCI_0_1 1

[1] "Convert CONFIG_ARMV7_PSCI_1_0 and CONFIG_ARMV7_PSCI_0_2 to Kconfig"

is handled as a firmware update object.
What efi_update_capsule() basically does is to load any firmware management
protocol (or fmp) drivers contained in a capsule, find out an appropriate
fmp driver and then invoke its set_image() interface against each binary
in a capsule.
In this commit, however, loading drivers is not supported.

The result of applying a capsule is set to be stored in "CapsuleXXXX"
variable, but its implementation is deferred to a fmp driver.

ed9349c697 efi_loader: capsule: add memory range capsule definitions
Memory range capsule gives us a way to notify that some memory regions
should be left untouched across the next reset.
See UEFI specification, section 8.5.3.

Since how we should handle this kind of capsule is totally up to
the system, no implementation will be added in this commit.

c74cd8bd08 efi_loader: capsule: add capsule_on_disk support
Capsule data can be loaded into the system either via UpdateCapsule
runtime service or files on a file system (of boot device).
The latter case is called "capsules on disk", and actual updates will
take place at the next boot time.

In this commit, we will support capsule on disk mechanism.

Please note that U-Boot itself has no notion of "boot device" and
all the capsule files to be executed will be detected only if they
are located in a specific directory, \EFI\UpdateCapsule, on a device
that is identified as a boot device by "BootXXXX" variables.

2bc27ca8a0 efi_loader: define UpdateCapsule api
In this commit, skeleton functions for capsule-related API's are
added under CONFIG_EFI_UPDATE_CAPSULE configuration.
Detailed implementation for a specific capsule type will be added
in the succeeding patches.

96ec4b1a18 common: update: fix an "unused" warning against update_flash()
Since update_flash() is used only in update_tftp(), it should be
guarded with appropriate config options.

After the commit 3149e524fc, common/update.c will be built under
either CONFIG_UDATE_TFTP, CONFIG_DFU_TFTP or CONFIG_UPDATE_FIT.
Since CONFIG_UPDATE_FIT, hence fit_update(), doesn't rely on
update_flash(), the compiler may cause an "unused" warning if
CONFIG_UPDATE_FIT=y and CONFIG_UPDATE_TFTP=n and CONFIG_DFU_TFTP=n.

This is, for example, the case for sandbox defconfig where
EFI_CAPSULE_FIRMWARE_FIT is enabled for test purpose.

Fixes: 3149e524fc ("common: update: add a generic interface for FIT
       image")
