This patch series introduces the basic ELF files support
for bootm command on MIPS based on kexec.
The goal of this work is ELF linux kernel loading for MIPS.
The patches 1-3 used to introduce per-arch low-level init for MIPS.
The patch 4 adds the nessesary low-level initialisation for
qemu-malta suitable for Linux kernel.
Just now barebox for MIPS32 has no support for cache, so
this patch series tries to overcome this disadvantage in
The patch 6 introduce memory region for loading ELFs on qemu-malta.
At last the patch 7 introduces kexec infrastructure for ELF loading.
* there is no Linux kernel cmdline support;
* the code is not clean (e.g. there are some '#if 0' and
some unused declarations);
* barebox already has ELF support for modules, but
this patch series just has no integration with it.
