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

Anyhow, any chance to get the kernel mainline fixed asap?

Many thanks and best regards
