Commit c3e2ee657418 ("MIPS: generic: Add support for zboot") added
support for self-extracting images to Generic MIPS. However, the
intended way to boot Generic MIPS kernels is using FIT Images and
UHI boot protocol, but currently there's no way to make self-extracting
FIT Image (only legacy uzImages).
This set consists of two parts:
1) various cleanups in arch/mips/boot/compressed/Makefile as a
prerequisite;
2) a new target named "vmlinuz.itb" for composing self-extracting
FIT Images, which allows to have the advantages of both UHI and
vmlinuz.
The second part involves some scenarios duplication, but I think it
can be a subject for another series (for constifying and unifying
FIT Images rules across the architectures).

It doesn't break anything on my end, so:
Acked-by: Paul Cercueil <[email protected]>
for the series.
Why vmlinuz.itb and not vmlinuz.fit or vmlinuz.uhi? Is the .itb suffix
already a thing?
Cheers,

Thanks!

As far as I know -- yes, ITB stands for Image Tree Blob (reference
to Device Tree Blob) and it's a standartized extension for FIT Images
(you can see that all variants for MIPS have ".itb" at the bottom of
arch/mips/boot/Makefile).
