What about the patch in attachment? It first tries to load
image as an ELF file. If this fails it falls back to raw
image load. Additionally, it takes feature of patch above to
go on even if no BIOS is found.
A slightly more polished version with less noisy messages is appended.
It also adjusts the ramdisk load address to physical addressing,
similiar to the binary kernel load.
One question I just found:
If we go on if no BIOS is found/executed and we load some
stuff to e.g. 0x80010000, where is the default address
translation made? As I understand MIPS, code in kseg0
(0x80000000) and kseg1 (0xA0000000) should be executable
without MMU/TLB setup because it is mapped by default to
physical 0x0. But looks to me that I get a
cpu_mips_handle_mmu_fault pc 80010000 ad 80010000 rw 2
is_user 0 smmu 1
for it.
