Re: [microblaze-uclinux] multiple microblaze processors

[Paul Hartke <phartke@xxxxxxxxxxxx>]

I've done this on the XUPV2P board which has the same FPGA as the ml310.

One issue to be aware of is that most boards only have one external memory
from which to execute from and Microblaze uclinux doesn't support SMP
and/or cache coherence.  A way to handle that is to statically partition
the external memory using the main_memory_{start, size} attributes in the
uclinux EDK os configuration tab.  Data can be passed between the two MBs
via FSL.

Actually sharing a memory region using mmap or the like is something I'd
like to look into but haven't gotten around to it yet.
