MTD_NAND_GPMI_NAND driver needs MXS_DMA to be selected, otherwise the following error happens
for imx_v6_v7_defconfig:

drivers/built-in.o: In function `gpmi_dma_filter':
clk-fixed-factor.c:(.text+0xb124c): undefined reference to `mxs_dma_is_apbh'
make: *** [vmlinux] Error 1

Ok, but what is the conclusion on this then? It has been 8 months
since that thread started and the problem is still present.

If we want to fix it, we can add the "depend on MXS-DMA" for gpmi nand.

Ok, I will submit a fix using "depends" then.

Thanks,
