This code is wrong for at least 4 reasons:
1) 0x8.... is just to access kseg0, it's not part of physical address
2) second argument is a size, not end
3) and it's lacking 0x
4) on yeeloong memory init doesn't use mmap.
Correct way is to replace:
grub_mm_init_region ((void *) modend, (grub_arch_memsize << 20)
- (modend - GRUB_ARCH_LOWMEMVSTART));
with:
grub_mm_init_region (0x81000000, 16 << 20);-- Regards Vladimir 'φ-coder/phcoder' Serbinenko
