I may just do this (reserve 64K) under INDIRECT_PIO for now, not sure
yet.
Probably we can make the first page of LOGIC_PIO a special region. It
could be a
reserved region when no legacy ISA bus present or overlay by MMIO in
case like
MIPS here.
Yeah, I could do that as well, but then I need special handling for that
region, which may complicate things.
Anyway, I'll cc you and linux-mips on any patch.
Thanks,
John
