[PATCH 0/9] Update clang support for ARM

[Tom Rini]

Hey all,

I decided to take a look again at what's needed to build and boot ARM
platforms when building with clang. The good news is that this generally
works now. Some size-constrained platforms don't build right now but I
was able to test a reasonable part of my lab. This series also depends
on:
https://patchwork.ozlabs.org/project/uboot/patch/20200604203515.12971-1-trini@konsulko.com/
to fix the warning there.

At this point LTO + clang requires a bit more work, and to use llvm-ld.
As the platform I was trying was still too large to link even with this,
I've set that investigation aside for now.

I've boot tested clang-16 on Pi 3 (32bit, 64bit, arm64) and
libretech-cc, and I'll be testing pine64_plus soon along with maybe
mx6cuboxi and seeing what the failures are on am65x_evm / j721e_evm
(these platforms require a bit more scripting on my part to make build
and test clean).
