[v2,2/3] mtd: nand: Let MTD_NAND_GPMI_NAND depend on MXS_DMA

From: Fabio Estevam <fabio.estevam@freescale.com>

MTD_NAND_GPMI_NAND driver depends on 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

Changes since v1:
- Use 'depends' rather than 'select'

I think  we can merget the patch 1 and patch 2 to one patch.

I am not sure on this, as they have clearly different purposes.

Patch 1 fixes the text file and include mx6.

Patch 2 fixes a build issue for mx6.

I prefer to keep them as seperate patches.

As mentioned elsewhere in this thread: We should not select user visible
options, so this patch is the only thing we can do atm (apart from
'fixing the tools' as David mentioned, but this is out of scope for an
-rc kernel)

Additionally the imx_v6_v7_defconfig should be adjusted so that the gpmi
nand driver actually gets built.

I asked Shawn about this and it seems that this patch is the way to go 
for the moment. So:

Acked-by: Dirk Behme <dirk.behme@gmail.com>

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
