This patch adds SPL support for IGEP-based boards.

Tested on an IGEPv2 Rev.C board with Micron NAND Flash memory.

Signed-off-by: Javier Martinez Canillas javier@dowhile0.org ---

Changes since v1: - Set NAND memory 200 Mhz timings when possible as suggested by Thomas Petazzoni

Changes since v2: - Add Numonyx 200MHz timings as suggested by Enric Balletbo i Serra
