Hello,
I am using MIPs-IDT79S334A.
just now i noted that there is no ioremap.c file in
source tree.
this made me to think if physical memory that is
normally
ioremapped is already a part of processor
memory map after startup
hence no need to call it explicitly in drivers .
Am i thinking right ..?
pls let me know .
Best Regards,
Atul

In which case the small green dots on your kernel source tree is the mould.
Time for an upgrade :-) Kernel's that don't have arch/mips/mm/ioremap.c
can only support ioremap() for physical addresses < 0x20000000.
