eff5a54758 cmd: zip: automatically pull in gzip()
Move the CONFIG_GZIP_COMPRESSED from a config.h macro to a Kconfig menu
item. It is not selectable by a user because there is no reason to do
so. Instead it will be automatically selected by the stuff which uses
gzip(), like the zip command.

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
option.

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/.

5972ff077e kconfig / kbuild: re-sync with Linux 4.18
Align Kconfig and Kbuild logic to Linux 4.18 release with minimal impact
on files outside of this scope.

Our previous Kconfig sync was done by commit e91610da7c ("kconfig:
re-sync with Linux 4.17-rc4").

A very small number of changes upstream since our sync with v4.17-rc4
that exist in the v4.18 release have already been applied here and have
been omitted from the list in this commit (and are readily available in
our own git history).

The imported Linux commits are:

ddb87a0b40 kbuild: remove unused dtc-version.sh script
This is U-Boot own code, and no longer used since commit 36dd5f1b8a
("dtc: Switch to building and using our own dtc unless provided").

Prior to that commit, U-Boot relied on an external dtc, so this script
was used to check the dtc version.

Now U-Boot bundles our own dtc in script/dtc/dtc like Linux kernel.

Users are still allowed to pass DTC= option from the command line,
but they are supposed to choose correct version of dtc in this case.
So, we do not check the dtc version any more.

67f2ee86cc kbuild: fixdep: Resync this with v4.17
The previous kbuild resync of e91610da7c ("kconfig: re-sync with Linux
4.17-rc4") accidentally did not sync the fixdep program.  This commit
brings fixdep in line with the rest of that previous resync.

This includes all of the following Linux kernel commits:
fbfa9be9904e kbuild: move include/config/ksym/* to include/ksym/*
5b8ad96d1a44 fixdep: remove some false CONFIG_ matches
14a596a7e6fd fixdep: remove stale references to uml-config.h

01b5cbe7012f fixdep: use malloc() and read() to load dep_file to buffer
41f92cffba19 fixdep: remove unnecessary <arpa/inet.h> inclusion
7c2ec43a2154 fixdep: exit with error code in error branches of do_config_file()

d8329e35cc08 fixdep: accept extra dependencies on stdin
4c835b57b8de fixdep: constify strrcmp arguments

Of note is that when applying dee81e988674 above our logic in that area
required some careful consideration to continue to apply.

8a266e5800 fixdep: fix U-Boot own code to handle only valid symbol characters
Currently, fixdep skips parsing include/linux/kconfig.h, but if it
parsed it, it would translate the following code in kconfig.h

  config_enabled(CONFIG_VAL(option##_MODULE)

into:

  $(wildcard include/config/option##/module.h)

When Kbuild includes .*.cmd, it would emit the following error:

  *** unterminated call to function 'wildcard': missing ')'.  Stop.

This issue prevents us from importing the upstream Linux commit
638e69cf2230 ("fixdep: do not ignore kconfig.h").

Fix this by handling only alphanumerical characters and underscores.
This makes sense because they match to the valid character sets in
Kconfig symbols.

As a side-note, you can reproduce this issue only on GNU Make <= 4.2.1

For GNU Make <= 4.2.1, the '#' always means the start of a comment.
Hence, GNU Make thinks the closing ')' is missing.

The following commit in GNU Make changed how it handles '#' in
function invocations. So, this does not happen for GNU Make 4.3
