Dear Alex Waterman,
> Moves to using newer defines and adds possible support for the
> second bank of RAM (if so desired).
>
> Also, some coding clean up: removed the needless define to 1s for
> defines that just act as flags.

Must be CONFIG_SYS_AT91_SLOW_CLOCK here.

Please follow the examples in at91sam9260ek.h
There is no CONFIG_USARTx anymore. Just defining
BASE and ID is sufficient.

Preferably those numeric constants should be replaced by defines from a
proper at91sam10g45.h....
