[U-Boot] [PATCH v7 04/19] imx: mx53ard: Add support for NAND Flash

2013-02-15 Thread Benoît Thébaudeau
Add support for the Samsung K9LAG08U0M NAND Flash (2-GiB MLC NAND Flash, 2-kiB pages, 256-kiB blocks, 30-ns R/W cycles, 1 CS) on mx53ard. eNFC_CLK_ROOT is set up with a cycle time of 37.5 ns (400 MHz / 3 / 5) for this board, which satisfies the 30-ns NF R/W cycle requirement. Signed-off-by: Benoî
