With libfdt support, we can take advantage of helper accessors in libfdt
for accessing the FDT header data. This makes the code more readable and
makes the FDT blob structure more opaque to the kernel. This also

Steven,
Looks like commit 198d208df (x86: Keep thread_info on thread stack in
x86_32) broke Xen's 32-bit PV guests.
I poked a little at it and it seems that at least the ifdef in
xen_cpu_up() needs to be adjusted to set up kernel_stack --- that allows
CPUs to get going. This is not enough
Changed in v4:
- cancelled i2c_imx-use_dma.
- changed Dma to DMA.
- add timeout handling for DMA transfer complete.
Changed in v3:
- fix a bug when request the DMA faild.
- some minor fixes for coding style.
- other minor fixes.
Changed in v2:
- remove has_dma_support property
- unify
Add i2c dts node properties for eDMA support, them depend on the eDMA driver.

Add dma support for i2c. This function depend on DMA driver.
You can turn on it by write both the dmas and dma-name properties in dts node.

Methods of accessing DMA contorller registers are inconsistent, some registers
are accessed by DMA_IN/OUT directly, while others are accessed by functions
get/set_* which are wrappers of DMA_IN/OUT, and even for the BCR register, it
is read by get_bcr

Some codes are calling chan_dbg with FSL_DMA_LD_DEBUG surrounded, it is really
unnecessary to use such a macro because chan_dbg is a wrapper of dev_dbg, we do
have corresponding DEBUG macro to switch on/off dev_dbg, and most of the other
codes are

These functions will be modified in the next patch in the series. By moving the
function in a patch separate from the changes, it will make review easier.

The usage of spin_lock_irqsave() is a stronger locking mechanism than is
required throughout the driver. The minimum locking required should be used
instead. Interrupts will be turned off and context will be saved, it is
unnecessary to use irqsave.

Hi Vinod Koul,
Please have a look at the v2 patch set.
v1 - v2 change:
The only one change is introducing a new patch[1/7] to remove the unnecessary
macro FSL_DMA_LD_DEBUG, thus the total patches number is 8 now (was 7)

KVM does not handle the reserved bits of x86 page tables correctly:
In PAE, bits 5:8 are reserved in the PDPTE.
In IA-32e, bit 8 is not reserved.
