I'm going to queue these even though its late in the cycle. I removed
the README from the patch though since I didn't think it was adding
much value.
Cheers,
Richard

this series should be harmless so including it is ok I believe.

I'm curious: the data sheet for the processor you mention in 4/4 says
that it ha 64K of RAM. Are there other processors in the range, or
have you done incredible things?

Heh,
64K is the internal sram..
There is a sdram controller DDR2 and a 32bit FlexBus bus for ROM/RAM
so I bet there is more...
Cheers
Andrea
P.S. I will notice right now an old m68k acker...

Hi Burton,

64KB is the internal static ram (SRAM), that's commonly 4 to 64K
for this family (i.e. some recent arm reachs 512K).
Then there is the built-in SDRAM/DDR2 controller :)
where i connect 128MB of DDR2(SDRAM), but other boards may have more.
Linux runs fine in ColdFire family from a long time. Initially only
non-MMU uClinux, now also the mainline kernel with MMU enabled.
Regards,
Angelo
