The uclinux.c mapping driver uses ioremap_nocache() to map its physical
mapping address to a system virtual address. Problem is that the region
it is mapping is not device memory. It is ordinary system RAM. On most
non-MMU systems this doesn't matter, and the mapping is always a 1:1
translation of the address.
But if we want to use the uclinux.c mapping driver on real MMU enabled
systems we should be using phys_to_virt() for the translation, since that
is really what we are doing. So change it to do that.

How can I compile-test this? Please, suggest a defconfig which compiles.
I created one but it does not build:
dedekind@blue:~/git/l2-mtd$ make ARCH=m68k CROSS_COMPILE=m68k-linux-
CHK include/linux/version.h
CHK include/generated/utsrelease.h
CALL scripts/checksyscalls.sh
CHK include/generated/compile.h
CC arch/m68k/kernel/time.o
arch/m68k/kernel/time.c:90:5: error: redefinition of 'arch_gettimeoffset'
include/linux/time.h:145:19: note: previous definition of 'arch_gettimeoffset'
was here
make[1]: *** [arch/m68k/kernel/time.o] Error 1
make: *** [arch/m68k/kernel] Error 2
It is attached.
Nothing attached?
In any case I would suggest:
make ARCH=m68k CROSS_COMPILE=m68k-linux- m5208evb_defconfig
Regards
Greg
