This patch adds support for a generic MMU-less Nios II board that
can be used e.g. for bare-metal compiler testing.  Nios II booting
is also tweaked so that bare-metal binaries start executing in RAM
starting at 0x00000000, rather than an alias at 0xc0000000, which
allows features such as unwinding to work when binaries are linked
to start at the beginning of the address space.
So why dont you just use the 10m50 GHRD for this , why do you need
custom board ?

I think because we wanted a board with no MMU, since our startup code
doesn't support that. Maybe Andrew can confirm/deny?

Yes, that's correct.

Thanks,

Andrew
