xilinx_spi: Split into platform and of driver, support new IP, platform independence.
v3 cover xilinx_spi: Split into platform and of driver, support new IP, platform independence.
Hi,
To follow is a series of patches against the xilinx_spi driver.
The patchset is against 2.6.32-rc6
The patchset addresses several problems in the current driver:
* It's PPC only (OF and uses PPC specific memory operations)
* Only supporting big endian writes
* Supports only 8bit SPI, support for DS570 (also 16 or 32 bit) is added.
* A platform driver is introduced for non OF capable architectures.
These patches were posted as one big patch up to 4 iterations, not splitted into 4.
This version, 3, is updated after review from Grant Likely and John Linn
John Linn has also tested the code on PPC, I have only tested on X86.

Applied to my 'test' branch on git.secretlab.ca. There was a conflict on patch 3/4 with a previous bugfix from John Linn. Please check that I've fixed it up correctly.
Cheers,

I think I reverted that change as Richard's fixes it I believe.

It is a real bug fix, and so should be in a separate patch.
