From: Huang Shijie shij...@gmail.com
[1] Why add these new DMA control commands?
In mx6q, the gpmi-nand driver is the only user of the APBH-DMA. The dma
clock
is enabled when we have successfully requested a DMA channel. So even when
the gpmi-nand driver does not work, the dma clock
,
the system has to enable the clock chain and it's parents ...
But with this patch, we only need to enable/disable dma clock one time,
just at we select the nand chip.
thanks

No, it is asking

Assume we have a 1GB(8Gb) nand chip, and we set the partitions

It is legit if we set the partitions as the following:
gpmi-nand:1g@200m(rootfs),100m@0(boot),100m@100m(kernel

patch that removes
CONFIG_MTD_NAND_VERIFY_WRITE from all defconfig files.
thanks a lot.
I will send out a separate patch to fix it.

I'd still prefer for this to be rather fixed. It seems to be able to find some
obvious mistakes etc.
could you please point out the mistakes?
thanks

In most of the time, the driver needs to check if the cts flow control
is enabled. But now, the driver checks the ASYNC_CTS_FLOW flag manually,
which is not a grace way. So add a new wraper function to make the code
tidy and clean.

parses out several mtd partitions right now.
This is obviously wrong. We even do not enable the gpmi-nand in
this case.
The patch comes from Artem's suggestion code which is better then mine.

For there are maybe only several partitions, i use the simple
Bubble sort algorithm.
