[U-Boot] [PATCH 7/7] imx27lite: add support for imx27lite board from LogicPD
Ilya Yanok
yanok at emcraft.com
Mon Jun 8 02:12:51 CEST 2009
This patch adds support for i.MX27-LITEKIT development board from
LogicPD. This board uses i.MX27 SoC and has 2MB NOR flash, 64MB NAND
flash, FEC ethernet controller integrated into i.MX27.
