Linux port availability for p5010 processor

Linux port availability for p5010 processor

Do we have a linux port available for freescale P5010 processor (with
single E5500 core) ?
*(found arch/powerpc/platforms/pseries ; and a some details on
kernel/cputable.c *)

Is there any reference board which uses this processor ? any reference in
DTS file also will be helpful.

Thanks
Vineeth

p5010 is basically a p5020 with one core and "memory complex" instead of
two.  The same Linux code should work for both.

pseries is something completely different.

p5020ds has a p5020.

Linux support is in arch/powerpc/platforms/85xx/p5020_ds.c (and
scattered in other places).

arch/powerpc/boot/dts/p5020ds.dts

found p5020_ds.c in platforms/85xx;
why is it a part of 85xx directory ? the core of P5020 is E5500 where the
core of 85xx is e500;

Do we have the processor initialization code (start.S, head.S) files, port
available with linux ?

e5500 is very similar to e500, so it's all part of the same family of cores=

e5500 is e500mc-64bit Power Architecture core.

So it should go head_64.S/entry_64.S with CONFIG_PPC_BOOK3E.
