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).
any reference in DTS file also will be helpful.
arch/powerpc/boot/dts/p5020ds.dts -Scott

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 ? On Wed, Dec 14, 2011 at 12:58 AM, Scott Wood [off-list ref]wrote:

e5500 is very similar to e500, so it's all part of the same family of cores= . --=20 Timur Tabi Linux kernel developer at Freescale=

e5500 is e500mc-64bit Power Architecture core.
Do we have the processor initialization code (start.S, head.S) files, port available with linux ?
So it should go head_64.S/entry_64.S with CONFIG_PPC_BOOK3E. Tiejun
