First, I think Shawn is on holiday at the moment. Second, recent kernel mainline from today building imx_v6_v7_defconfig is broken due to this. So to make it build again, we have to enable CONFIG_MXS_DMA anyhow. As it seems that GPMI_NAND needs it to build, I would vote for the depends on MXS_DMA fix proposed by Richard http://www.spinics.net/lists/arm-kernel/msg186111.html Anyhow, any chance to get the kernel mainline fixed asap? Many thanks and best regards Dirk
