I asked Shawn about this and it seems that this patch is the way to go for the moment. So: Acked-by: Dirk Behme <redacted> David: Artem: Building recent 3.6-rc1mainline with imx_v6_v7_defconfig is broken. We need this patch to get it working, again. It would be nice if this patch could go as a fix into 3.6-rcX mainline asap. Could you help with this? Many thanks and best regards Dirk
Additionally the imx_v6_v7_defconfig should be adjusted so that the gpmi nand driver actually gets built. Saschaquoted
