It doesn't work for me.

I need something that if an e500v2 platform (e.g. the P1022DS) is
selected, then I won't be able to select any e500mc platforms (e.g.
P4080DS).  And if I don't select any e500v2 platforms, then I will be
able to select an e500mc platform.  This patch doesn't seem to do

It might be necessary to split the entire menu into two parts, one for
e500v2 parts and one for e500mc parts.
