This board is a plug in card for Marvell's switch system development kits. Form-factor aside it is similar to the DB-88F6820-GP with the following differences. - TCLK is 200MHz - SPI1 is used - No SATA - No MMC - NAND flash Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Chris Packham <judge.packham@gmail.com> Signed-off-by: Stefan Roese <sr@denx.de>
