[PATCH mips-next 0/2] mips: boot: add support for self-extracting FIT images (vmlinuz.itb)

[Alexander Lobakin]

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).
