I'm looking for U-boot support for the embedded SPI driver on the
MPC8536 to access a SPI flash device (Numonyx [ex-STmicro] M25P16).  The
eSPI can read the SPI flash (that's how U-boot gets loaded into RAM) and
I can read/write from linux using the mtdblock driver.  I see code that
appears to support the MPC83xx, but it looks quite different than the
MPC85xx.  I am willing to backport the linux code to work in U-boot, but
am hoping that isn't necessary.
