Hi WolfSang:
I mis-understand your meaning of the IO-Accessors.
It maybe work when the IO-Accessors are used.
Wait a minute, I would resend the patches use he IO-Accessors methods.

Hi Wolfsang:
Maybe I don't describe my thoughts clearly and exactly.
I feel it's not easy to add the the IO-accessors in every cmd execution
procedure, to make
a double check why a IO-accessor is needed or not.

Some SD host controllers (noticed on an integrated JMicron SD reader
on an HP Pavilion dv5-1250eo laptop) don't update the dma address
register before signalling a dma interrupt due to a dma boundary.
Detect this and update the register to the next 512KB boundary,

Out of sheer curiosity, Qualcomm/CodeAurora guys:
if you dump out the registers at offset 0xfe0-0xfff on the
SDCC, does it contain a valid PrimeCell ID? Anyone who
can make a hexdump of it?
It is possible to hardcode an AMBA ID to use this driver
even if this area is just 0x... but I'm just c

This adds the mmc host driver for Freescale MXS-based SoC i.MX23/28.
The driver calls into mxs-dma via generic dmaengine api for both pio
and data transfer.
Thanks Chris Ball for the indentation patch.

Just to make sure, because all the other patches are for mx53: Do you
have tested it on mx25/35/51 also?
