This series comprises error corrections for the UEFI subsystem:
* correct consideration of timestamps for variable authentication

- Resync Kconfiglib with the v14.1.0 release.
- Re-sync our <linux/compiler*h> files with v5.7-rc5 from upstream.
- Fully resync checkpatch.pl with v5.7 release.
To safely to all of the above, we have a few bugfixes about functions
that need a 'static inline' but weren't. We also stop setting
CROSS_COMPILE in arch/*/config.mk. Finally, with the above changes
boards can now opt-in to optimizing inlining and we do this for the
socfpga stratix10 platform for space savings.
Export the UEFI sub-system initialization state. This will allow to treat
the setting of UEFI variables during and after initialization differently.

Use correct printf code in efi_image_parse().
Add random number generation to HTML documentation.
This reverts commit 0486497e2b.
The strtoul has well-defined semantics. It is defined by the C standard and
POSIX. To quote the relevant section of the man pages,
> If base is zero or 16, the string may then include a "0x" prefix, and the
> number will be read in base 16; otherwise, a zero base is taken as 10
> (decimal) unless the next character is '0', in which case it is taken as
> 8 (octal).
Keeping these semantics is important for several reasons. First, it is very
surprising for standard library functions to behave differently than usual.
Every other implementation of strtoul has different semantics than the
implementation in U-Boot at the moment. Second, it can result in very
surprising results from small changes. For example, changing the string
"1f" to "20" causes the parsed value to *decrease*. Forcing use of the "0x"
prefix to specify hexidecimal numbers is a feature, not a bug. Lastly, this
is slightly less performant, since the entire number is parsed twice.
This fixes the str_simple_strtoul test failing with
test/str_ut.c:29, run_strtoul(): expect_val == val: Expected 0x44b (1099), got 0x1099ab (1087915)
test/str_ut.c:46, str_simple_strtoul(): 0 == run_strtoul(uts, str2, 0, 1099, 4): Expected 0x0 (0), got 0x1 (1)
