strn(cat|cpy) has a bad habit of not nul-terminating the destination,
resulting in constructions like
strncpy(foo, bar, sizeof(foo) - 1);
foo[sizeof(foo) - 1] = '\0';
However, it is very easy to forget about this behavior and accidentally
leave a string unterminated. This has shown up in some recent coverity
scans [1, 2] (including code recently touched by yours truly).
Fortunately, the guys at OpenBSD came up with strl(cat|cpy), which always
nul-terminate strings. These functions are already in U-Boot, so we should
encourage new code to use them instead of strn(cat|cpy).

Sometimes it is useful to boot OS with already fixed-up
device tree. Check for env variable 'skip_board_fixup'
before calling ft_board_setup().
Current behaviour is unchanged, additionally user can
set skip_board_fixup to 1 to skip the fixup.

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.

The 'debug' and 'printf' functions were previously added to the list of
logFunctions in commit 0cab42110d ("checkpatch.pl: Add 'debug' to
the list of logFunctions") and commit 397bfd4642 ("checkpatch.pl:
Add 'printf' to logFunctions") but these additions were lost when newer
versions of checkpatch were pulled in from the upstream Linux
kernel version.
This restores them so that you don't end up in a situation where
checkpatch will give a warning for "quoted string split across lines"
which you cannot fix without getting a warning for "line over 80
characters" instead.

Checkpatch produces the following warning:
Unescaped left brace in regex is deprecated here
(and will be fatal in Perl 5.30), passed through in regex;
marked by <-- HERE in m/^(\+.*(?:do|\))){ <-- HERE /
at scripts/checkpatch.pl line 3348.
The curent checkpatch of the Linux kernel corrects this
bug and many others.
It provides improved colored output.
So replace checkpatch by the current Linux version.
Add an empty file scripts/const_structs.checkpatch.
We can later fill it according to our needs.

They are located under tools/ directory in U-Boot now.

It is true that binutils-version.sh and dtc-version.sh
do not originate in Linux Kernel, but they should
