DESCRIPTION
-----------

The patch provides the spi_xfer funtion, which used by cmd_spi.c to
support the sspi command for all at91rm9200 boards.

This patch is based on Ulf Samuelsson's at45 split patch, but don't
include this

Applying this patch will crash existing AT91RM9200 boards since the 
subroutines will be defined in two files.
board/<board>/at45.c must not be built.

Also, it is not recommended to run the SPI faster than 5  Mbps
unless you really know what you are doing.

The at45split patch is still in the patch queue, and Peter said he
should be able to review it this week.
