In commit 4963f63f ("image: Use gd->ram_base/_size in
env_get_bootm_size()") the size of the available memory for U-Boot to
use when relocating images, and not otherwise constrained, was changed
to include all known memory banks. In the case of this platform however,
all of the memory known to U-Boot is not also part of the Linux kernel
"lowmem" and so we must use CFG_SYS_BOOTMAPSZ to limit where we relocate
images to. We set a conservative limit of 256MB here to mirror the
previous behavior.

Update the zstd implementation to match Linux zstd 1.5.2 from commit
2aa14b1ab2.

This was motivated by running into decompression corruption issues when
trying to uncompress files compressed with newer versions of zstd. zstd
users also claim significantly improved decompression times with newer
zstd versions which is a side benefit.

Original zstd code was copied from Linux commit 2aa14b1ab2 which is a
custom-built implementation based on zstd 1.3.1. Linux switched to an
implementation that is a copy of the upstream zstd code in Linux commit
e0c1b49f5b, this results in a large code diff. However this should make
future updates easier along with other benefits[1].

This commit is a straight mirror of the Linux zstd code, except to:
- update a few #include that do not translate cleanly
  - linux/swab.h -> asm/byteorder.h
  - linux/limits.h -> linux/kernel.h
  - linux/module.h -> linux/compat.h
- remove assert() from debug.h so it doesn't conflict with u-boot's
  assert()
- strip out the compressor code as was done in the previous u-boot zstd
- update existing zstd users to the new Linux zstd API
- change the #define for MEM_STATIC to use INLINE_KEYWORD for codesize
- add a new KConfig option that sets zstd build options to minify code
  based on zstd's ZSTD_LIB_MINIFY[2].

These changes were tested by booting a zstd 1.5.2 compressed kernel inside a
FIT. And the squashfs changes by loading a file from zstd compressed squashfs
with sqfsload. buildman was used to compile test other boards and check for
binary bloat, as follows:

> $ buildman -b zstd2 --boards dh_imx6,m53menlo,mvebu_espressobin-88f3720,sandbox,sandbox64,stm32mp15_dhcom_basic,stm32mp15_dhcor_basic,turris_mox,turris_omnia -sS

The current support for updating variables in a binary is hard-coded to
work with U-Boot:

- It assumes the image starts at __image_copy_start
- It uses the existing U-Boot-specific entry types

It is useful for other projects to use these feature.

Add properties to enable writing symbols for any blob, a way of specifying
the base symbol and a way of providing the ELF filename to allow symbol
lookup to take place.

With this it is possible to update a Zephyr image, such as zephyr.bin
after it has been built.

Instead of the bash script, use binman to generate the FIT for arm64.

For 32-bit boards, use binman for all images, dropping the intermediate
files.

With this change, only Zynq is now using SPL_FIT_GENERATOR so update the
Kconfig rule accordingly.

Clean up the Makefile to the extent possible. Unfortunately, two boards
do not use SPL_FRAMEWORK so don't enable the u-boot.img rule:

   evb-rk3036
   kylin-rk3036

So a small remnant remains.

Add the required binman images to replace the Makefile rules which are
currently used. This includes subsuming:

   - tpl/u-boot-tpl-rockchip.bin if TPL is enabled
   - idbloader.img if either or both of SPL and TPL are enabled
   - u-boot.itb if SPL_FIT is enabled
   - u-boot-rockchip.bin if SPL is used, either using u-boot.itb when
     SPL_FIT is enabled or u-boot.img when it isn't

Note that the intermediate files are dropped with binman, since it
producing everything in one pass. This means that
tpl/u-boot-tpl-rockchip.bin is not created, for example.

Note that for some 32-bit rk3288 boards, rockchip-optee.dtsi is included.

OP-TEE has a format with a binary header that can be used instead of the
ELF file. With newer versions of OP-TEE this may be required on some
platforms.

Add support for this in binman. First, add a method to obtain the ELF
sections from an entry, then use that in the FIT support. We then end up
with the ability to support both types of OP-TEE files, depending on which
one is passed in with the entry argument (TEE=xxx in the U-Boot build).

At present only the image (which is a section) has a filename. Move this
implementation to the entry_Section class so that any section can have a

This breaks chromebook_coral and it is also not how things should work. If
a board needs to bind GPIOs as part of a pinctrl driver this can be done
during the bind step, if needed.

We cannot probe pinctrl devices when binding as a rule, since it cannot be
supported on some platforms.

The bind and probe steps are separate in U-Boot and they should remain
separate.

This board is useful for benchmarking overall U-Boot performance. Enable
the bootstage feature so we get a report.

Since this returns to the boot rom before finishing executing
board_init_r() in SPL, add a few bootstage calls so that we can collect
timing from TPL.

For the stash region, use a portion of SRAM, 64KB below the stack top.
This allows the TPL image to be up to nearly 120KB (it is typically about
64KB). SPL normally runs from SDRAM at 0, so can use the same stash
region.
