blackfin: fix undefined reference to srand and rand
Commit 9ba9e85f3f1c (net: Fix NET_RANDOM_ETHADDR dependencies)
accidentally dropped CONFIG_LIB_RAND defines for 14 Blackfin boards.
Prior to that commit, those boards defined CONFIG_LIB_RAND, but not
CONFIG_NET_RANDOM_ETHADDR. So, commit 9ba9e85f3f1c should not have
touched them, but in fact it ripped CONFIG_LIB_RAND off from all the
header files, which caused undefined reference to srand and rand.
CONFIG_LIB_RAND=y must be revived for such boards.
BTW, this commit indeed makes it better, but even with this fix,
three boards (bf533-stamp, bf538f-ezkit, cm-bf548) still can not
build due to region 'ram' overflowed error. This was cause by
commit 6eed3786c68c (net: Move the CMD_NET config to defconfigs)
because CMD_NET selects NET, and NET selects REGEX. Eventually,
some boards were newly enabled with CONFIG_REGEX, increasing the
memory footprint. A patch is expected to fix the build error.

lib: zstd: update to latest Linux zstd 1.5.2
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
