I think the kernel can go either way.  It can handle 1 big bank or 7
banks.  The parts that were broken in the past were:
* U-boot would refuse to tell the kernel about more than 4 banks
(that's what my patch fixed).
* The kernel choked if it was told about a bogus 8th bank that started
at 0 and was 0 bytes big.

What about if we just take my patch to support more than 4 banks
(Vadim now has good justification for needing it)?  ...and then we'll
fix our U-Boot not to tell the kernel about a bogus 8th bank (that was
just a bug in our config file).
