do we know the size of the first memory chunk early enough in head.S?
Maybe it's time to increase INIT_MAPPED_SIZE at least in cases where
we know that there's more than 4 MB in the first memchunk ...
"get_bi_record BI_MEMCHUNK" will return a pointer to the first mem_info
struct.
Yep, that's as far as I got - if I read bootinfo.h right, this will need to
have an offset of 12 bytes added to get to the size member, correct?
Nope, only 4. A0 points to the bootinfo record payload, which is of
type struct mem_info * in this case:
movew %a0@(BIR_SIZE),%d0
lea %a0@(BIR_DATA),%a0
