Subject: [PATCH] Add support for Lyrtech SFF-SDR board (ARM926EJS)
To: SFFSDR@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).
