d721001fd6 net: Move the checksum functions to lib/
These functions are used by code outside the network support, so move them
to lib/ to be more accessible.

Without this, the functions are only accessible in SPL/TPL only if
CONFIG_SPL/TPL_NET are defined. Many boards do not enable those option but
still want to do checksums in this format.

Fix up a few code-style nits while we are here.

3c10dc95bd binman: Add a library to access binman entries
SPL and TPL can access information about binman entries using link-time
symbols but this is not available in U-Boot proper. Of course it could be
made available, but the intention is to just read the device tree.

Add support for this, so that U-Boot can locate entries.

At present there is only one control for this and it is used for both SPL

47870afab9 initcall: Move to inline function
The board_r init function was complaining that we are looping through
an array, calling all our tiny init stubs sequentially via indirect
function calls (which can't be speculated, so they are slow).

The solution to that is pretty easy though. All we need to do is inline
the function that loops through the functions and the compiler will
automatically convert almost all indirect calls into direct inlined code.

With this patch, the overall code size drops (by 40 bytes on riscv64)
and boot time should become measurably faster for every target.

51c2345bd2 Roll CRC16-CCITT into the hash infrastructure
The CRC16-CCITT checksum function is useful for space-constrained
applications (such as obtaining a checksum across a 2KBit or 4KBit
EEPROM) in boot applications. It has not been accessible from boot
scripts until now (due to not having a dedicated command and not being
supported by the hash infrstructure) limiting its applicability
outside of custom commands.

This adds the CRC16-CCITT (poly 0x1021, init 0x0) algorithm to the
list of available hashes and adds a new crc16_ccitt_wd_buf() to make
this possible.

d677bfe2f7 tpm: disociate TPMv1.x specific and generic code
There are no changes in this commit but a new organization of the code
as follow.

* cmd/ directory:
        > move existing code from cmd/tpm.c in cmd/tpm-common.c
	> move specific code in cmd/tpm-v1.c
	> create a specific header file with generic definitions for
	  commands only called cmd/tpm-user-utils.h

* lib/ directory:
        > move existing code from lib/tpm.c in lib/tpm-common.c
	> move specific code in lib/tpm-v1.c
	> create a specific header file with generic definitions for
	  the library itself called lib/tpm-utils.h

* include/ directory:
        > move existing code from include/tpm.h in include/tpm-common.h
	> move specific code in include/tpm-v1.h

Code designated as 'common' is compiled if TPM are used. Code designated
as 'specific' is compiled only if the right specification has been
selected.

All files include tpm-common.h.
Files in cmd/ include tpm-user-utils.h.
Files in lib/ include tpm-utils.h.
Depending on the specification, files may include either (not both)
tpm-v1.h or tpm-v2.h.

9f9ce3c369 tpm: prepare introduction of TPMv2.x support in Kconfig
Because both major revisions are not compatible at all, let's make them
mutually exclusive in Kconfig. This way we will be sure, when using a
command or a library function that it is supported by the right
revision.

Current drivers are currently prefixed by "tpm_", we will prefix TPMv2.x
files by "tpm2_" to make the distinction without moving everything.

The Kconfig menu about TPM drivers is now divided into two sections, one
for each specification. Compliant drivers with one specification will
only show up if this specification _only_ has been selected, otherwise a
comment is displayed.

Once a driver is selected by the user, it selects automatically a
boolean value, that is needed in order to activate the TPM commands.
Selecting the TPM commands will automatically select the right
command/library files.

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.

05ef48a248 efi_driver: EFI block driver
This patch provides
* a uclass for EFI drivers
* a EFI driver for block devices

For each EFI driver the uclass
* creates a handle
* adds the driver binding protocol

The uclass provides the bind, start, and stop entry points for the driver
binding protocol.

In bind() and stop() it checks if the controller implements the protocol
supported by the EFI driver. In the start() function it calls the bind()
function of the EFI driver. In the stop() function it destroys the child
controllers.

The EFI block driver binds to controllers implementing the block io
protocol.

When the bind function of the EFI block driver is called it creates a
new U-Boot block device. It installs child handles for all partitions and
installs the simple file protocol on these.

The read and write functions of the EFI block driver delegate calls to the
controller that it is bound to.

A usage example is as following:

U-Boot loads the iPXE snp.efi executable. iPXE connects an iSCSI drive and
exposes a handle with the block IO protocol. It calls ConnectController.

Now the EFI block driver installs the partitions with the simple file
protocol.

iPXE uses the simple file protocol to load Grub or the Linux Kernel.

Commit 94e3c8c4fd ("crypto/fsl - Add progressive hashing support
using hardware acceleration.") created entries for CONFIG_SHA1,
CONFIG_SHA256, CONFIG_SHA_HW_ACCEL, and CONFIG_SHA_PROG_HW_ACCEL.
However, no defconfig has migrated to it.  Complete the move by first
adding additional logic to various Kconfig files to select this when
required and then use the moveconfig tool.  In many cases we can select
these because they are required to implement other drivers.  We also
correct how we include the various hashing algorithms in SPL.

This commit was generated as follows (after Kconfig additions):

[1] tools/moveconfig.py -y SHA1 SHA256 SHA_HW_ACCEL
[2] tools/moveconfig.py -y SHA_PROG_HW_ACCEL

Note:
We cannot move SHA_HW_ACCEL and SHA_PROG_HW_ACCEL simultaneously
because there is dependency between them.

d2d9bdfcf9 spl: saveenv: adding saveenv support in SPL
By default saveenv option is not supported for SPL. This patch
enable the support for save environment variable for SPL build.

Enable save environment support in SPL after setenv. By default
the saveenv option is not provided in SPL, but some boards need
this support in 'Falcon' boot, where SPL need to boot from
different images based on environment variable set by OS. For
example OS may set "reboot_image" environment variable to
"recovery" inorder to boot recovery image by SPL. The SPL read
"reboot_image" and act accordingly and change the reboot_image
to default mode using setenv and save the environemnt.

76f1f38816 Use separate options for TPL support
At present TPL uses the same options as SPL support. In a few cases the board
config enables or disables the SPL options depending on whether
CONFIG_TPL_BUILD is defined.

With the move to Kconfig, options are determined for the whole build and
(without a hack like an #undef in a header file) cannot be controlled in this
way.

Create new TPL options for these and update users. This will allow Kconfig
conversion to proceed for these boards.

51c14cd128 verified-boot: Minimal support for booting U-Boot proper from SPL
This allows a board to configure verified boot within the SPL using
a FIT or FIT with external data. It also allows the SPL to perform
signature verification without needing relocation.

The board configuration will need to add the following feature defines:
CONFIG_SPL_CRYPTO_SUPPORT
CONFIG_SPL_HASH_SUPPORT
CONFIG_SPL_SHA256

In this example, SHA256 is the only selected hashing algorithm.

And the following booleans:
CONFIG_SPL=y
CONFIG_SPL_DM=y
CONFIG_SPL_LOAD_FIT=y
CONFIG_SPL_FIT=y
CONFIG_SPL_OF_CONTROL=y
CONFIG_SPL_OF_LIBFDT=y
CONFIG_SPL_FIT_SIGNATURE=y

aa34fbc087 fdt: Allow libfdt to be used in SPL
Add an option to enable libfdt in SPL. This can be useful when decoding
FIT files in SPL.

We need to make sure this option is not enabled in SPL by this change.
Also this option needs to be enabled in host builds. Si add a new
IMAGE_USE_LIBFDT #define which can be used in files that are built on the
host but must also build for U-Boot and SPL.

15b51878be Makefile: remove BUILD_TAG from KBUILD_CFLAGS
If BUILD_TAG is part of KBUILD_CFLAGS, then any time the value changes,
all files get rebuilt. In a continuous integration environment, the value
will change every build. This wastes time, assuming that incremental
builds would otherwise occur.

To solve this, remove BUILD_TAG from KBUILD_CFLAGS and add it to CFLAGS
for just the one file that uses it. This does have the disadvantage that
if any other files want to use the flag, we'll need to duplicate this
custom CFLAGS setup logic. However, it seems unlikely we'll need this.

An alternative would be to add BUILD_TAG to the "local version" and remove
the special case code from display_options.c. However, that would affect
the format of the U-Boot signon message, which may negatively affect
people looking for specific data there. The approach of using
file-specific CFLAGS was suggested by Masahiro Yamada.
