+Subject: [PATCH] Add support for Lyrtech SFF-SDR board (ARM926EJS)
+To: SFFSDR at LISTSERV.VT.EDU
+Precedence: list
+
+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).
