[PATCH v5 0/4] Fix compiler warnings for 32-bit ARM

[Simon Glass]

These were noticed when building sandbox on a Raspberry Pi 400, which uses
32-bit linux.

To make this work, I enabled CONFIG_HOST_32BIT in 'make menuconfig'. It
would be nice if that were automatic, since we have the logic already in
arch/sandbox/config.mk

So this series adds that.

It also fixes the unicode warnings of the form:

/usr/bin/ld: warning: arch/sandbox/cpu/start.o uses 2-byte wchar_t yet the
output is to use 4-byte wchar_t; use of wchar_t values across objects
may fail

as suggested by Heinrich.

Changes in v5:
- Resync with upstream instead

Changes in v4:
- Rebase to master
- Use $(HOSTCC) instead of gcc
- Add proper Kconfig help

Changes in v3:
- Change some things EFI things missed (or new since) last time
- Use 'bitness' instead of 'bit'
- Add a new patch to change non-EFI occurences

Changes in v2:
- Drop patches previously applied
- Put all the packages in gcc.rst

Simon Glass (4):
  scripts/checkpatch.pl: Resync with v5.16
  efi: Use 16-bit unicode strings
  sandbox: Detect the host bit size automatically
  treewide: Use 16-bit unicode strings
