More AP / SP bits for the 34K, the Malta bits and things. Still wants

a little polishing.

help
The loader can use memory that is present but has been hidden from
Linux using the kernel command line option "mem=xxMB". It's up to
you to ensure the amount you put in the option and the space your
program requires is less or equal to the amount physically present.

help
Vectored interrupt mode allowing faster dispatching of interrupts.
The board support code needs to be written to take advantage of this
mode. Compatibility code is included to allow the kernel to run on
a CPU that does not support vectored interrupts. It's safe to
say Y here.
