[Qemu/PearPC] Question w.r.t. ``starting with 0x1E0'' in motorola_powerpc/README.OTHERBOARDS

[Karel Gardas]

Short followup: I've found that Qemu when started in PREP more (-M prep 
command-line option), seems to emulate `Mesquite cPCI (MCP750)' board, at 
least booted linux claims this in /proc/cpuinfo. Also this board seems to 
be supported in RTEMS, so my hopes to get it working together still 
remain.

Cheers,
Karel
