-Philip,
-this is the patch I´m planning on sending to the U-Boot
-folks so that the SFFSDR is integrated into mainline
-U-Boot.
-
-It is mostly based on the work you have done.
-
-I added code to make the EEPROM accessible through
-the I2C bus. This is needed because we use an I2C
-switch on the SFFSDR that is turned OFF by default.
-I also added code to read the MAC address from the
-EEPROM.
-
-I also removed unused stuff specific to the
-Schmoogie board.
-
-The network and NAND are both working fine with
-that patch.
-
-I´m looking forward to your comments.
-
-Hugo V.

-This patch adds support for the Lyrtech SFF-SDR, based
-on the TI DaVinci architecture (ARM926EJS).
