This patch set does two things about the MXS-DMA:
[1] patch 1 ~ patch 5: move the mxs dma header to a more common place.
Beside the mx23/mx28, the APBH-DMA is also used by MX50 and MX6Q.
So move the mxs dma header file to a more common place, and rename
it to mxs-dma.h
[2] patch 6 ~ patch 10: rewrite the last parameter of mxs_dma_prep_slave_sg().
In the new GPMI version, some hardware behavior changes.
The WAIT4END bit should be set in the middle one of the ECC READ page
DMA chain.
The DMA chain should be set like this:
+-----+ +-----+ +-----+
| cmd | ------------> | cmd | ------------------> | cmd |
+-----+ +-----+ +-----+
^ ^

set WAIT4END here too set WAIT4END here
