Attached is a patch that adds hardware SPI support for the MPC834x CPU,
and as an example, the MPC8349EMDS evaluation board.  The only new
configuration option is CONFIG_HARD_SPI.  Andy Fleming made a good
suggestion of putting the driver code in /drivers.  I don't think the
driver is generic enough at this time (depends heavily on the MPC8349's
internal memory map), so for now it's in /cpu/mpc83xx.  If future SPI
controllers use the same data structures this will be easy to port.


Added hardware SPI functionality for MPC834x-based boards.
Communications over the SPI bus can be performed either through the
spi_xfer() function call or via the 'sspi' command which is enabled by
