[PATCH 00/17] Various toolchain compatibility fixes/improvements

[Sam Edwards]

Long time no see, U-Boot folks!

This patchset consists of various bug fixes and correctness improvements that
I discovered while attempting to add first-class LLVM support to the build
system. These patches are NOT related to LLVM support directly; rather, they
address existing issues that should be resolved regardless of future changes.
For the most part, the patches are mutually independent and can be reviewed and
applied separately. If any patch is not suitable for merging now, feel free to
skip it: I will incorporate feedback and revisit those changes as part of the
upcoming LLVM support patchset. I'd like this patchset to be evaluated on its
own merits, based on the current state of the code, without consideration for
future LLVM support.

Note that the issues addressed in this patchset do not occur when U-Boot is
built using the GCC/GNU toolchain. These bugs seem to be specific to builds
using other toolchains, like LLVM, and do not appear to affect users relying on
GCC/GNU. Therefore, I see no need to rush these changes into the stable branch.

Again, these patches are mostly independent/reorderable...
...except that: "arm: Add aligned-memory aliases to eabi_compat"
...depends on: "arm: Add __aeabi_memclr in eabi_compat"

Warm regards,
Sam
