c57383b0c2 checkpatch.pl: Fully re-sync with v5.7
While commit 048a648298 ("checkpatch.pl: Update to v5.7") largely
re-syncs us with checkpatch.pl from v5.7 there are a number of things
missing still.  Re-copy the script and again take care to keep our
allowed debug prints and now localized checks intact.

a9610bd8e4 kconfig: Add scripts/Kconfig.include from v4.19
As part of re-syncing our Kconfig logic up to v4.19, we had missed
adding this new file that includes helper macros.  To quote the upstream
commit e1cfdc0e72fc ("kconfig: add basic helper macros to scripts/Kconfig.include"):

Kconfig got text processing tools like we see in Make.  Add Kconfig
helper macros to scripts/Kconfig.include like we collect Makefile
macros in scripts/Kbuild.include.

Move the CONFIG_GZIP_COMPRESSED from a config.h macro to a Kconfig menu

so. Instead it will be automatically selected by the stuff which uses

Remove it from the config_whitelist.txt. Also remove
CONFIG_GZIP_COMPRESS_DEF_SZ as this was never used on any board. The
default seems to be sane, otherwise it should be added as a Kconfig

e519f03a18 cmd: mem: Remove CONFIG_SYS_MEMTEST_SCRATCH mapping
There is no real need to exactly define space for saving patterns for
alternate memory test. It is much easier to allocate space on the stack and
use it instead of trying to find out space where pattern should be saved.

For example if you want to test the whole DDR memory you can't save patter
to DDR and you need to find it out. On Xilinx devices DDR or OCM addresses
were chosen but that means that OCM needs to be mapped and U-Boot has
access permission there.

It is easier to remove this limitation and simply save it on stack because
it is very clear that memory test can't rewrite U-Boot and U-Boot has also
full access to memory where runs from.

15c160301c scripts/get_default_envs.sh: preserve order of multiple entries for same variable
It's possible that the default_environment[] array contains multiple
entries for the same variable, e.g. a setting from env_default.h based
on some CONFIG_* variable, and another from
CONFIG_EXTRA_ENV_SETTINGS. In such a case, the last setting takes
effect.

Hence, in order to be able to use the output from this script as an
CONFIG_DEFAULT_ENV_FILE and get the same default environment as one
currently has, we need to preserve the order. So only sort by the
variable name, and disable the last-resort comparison.

We could pipe the result through uniq to remove duplicate lines, but I
think there's some value in seeing that certain variables are defined
multiple times.

f34d0ad82e kbuild: SPL/TPL: generate separate asm-offsets.h for SPL and TPL
Currently generic-asm-offsets.h and asm-offsets.h are generated based
on U-Boot proper config options. The same asm-offsets headers are used
for building U-Boot SPL/TPL, which causes potential offset mismatch if
U-Boot proper has different config options from U-Boot SPL/TPL.

This commit adds:
  spl/include/generated/(generic-)asm-offsets.h
  tpl/include/generated/(generic-)asm-offsets.h

spl/include/generated/(generic-)asm-offsets.h is generated if
CONFIG_SPL=y, and included when building SPL.

tpl/include/generated/(generic-)asm-offsets.h is generated if
CONFIG_TPL=y, and included when building TPL.

They are created before Kbuild descends into SPL/TPL object directories
and builds $(obj)/dts/dt-platdata.o because $(obj)/dts/dt-platdata.c
includes a bunch of headers.

Prepend -I$(obj)/include to $(UBOOTINCLUDE) so (generic-)asm-offsets.h
is searched in {spl,tpl}/include/generated/.

is useless.

Adopt the Linux kernel script
scripts/coccinelle/api/alloc/alloc_cast.cocci.

Now 'make coccicheck' generates warnings like:

./drivers/ata/fsl_sata.c:143:29-33:
WARNING: casting value returned by memory allocation function
to (void *) is useless.

308c6b0d4b fixdep: Re-sync with Linux 5.7-rc1
fixdep is a standalone host program, so we can just re-sync it with
the latest Linux in one commit.

I kept the U-Boot own code block surrounded by
/* hack for U-Boot */ ... /* U-boot hack end */.
