BSPs for Motorola PowerPC MVME230x boards

The BSP named "motorola_shared" is the common source
for nearly all Motorola VME and CompactPCI boards.
The MVME2301 - MVME2304 are 603e based and vary in
the amount of memory.  The MVME2305 - MVME2308 are
604 based and also vary in the amount of memory.

Look at the source in c/src/lib/libbsp/powerpc/motorola_shared
and the configuration files make/custom/mvme2307.cfg and
make/custom/mcp750.cfg for boards based on motorola_shared.
There are some READMEs in the motorola_shared directory
which give useful information on how the bsp is adapted
to the various boards.

It should work or be minor tweaks.  There is a recent patch to
the start code for one of the 603e based boards.

The BSP supports all the basic functions on the board including

OK.  Prebuilt binaries are available for Cygwin on NT.

You can use the Bug's standard features to do this.

gdb has remote debugging support for the ROM monitor on this board
and there is remote task aware debugging via Ethernet as well.
