As suggested by Andrew Morton, remove memzero() - it's not supported
on other architectures so use of it is a potential build breaking bug.
Since the compiler optimizes memset(x,0,n) to __memzero() perfectly
well, we don't miss out on the underlying benefits of memzero().

This updates most of the OMAP drivers which are in mainline to switch to
using the cross-platform GPIO calls instead of the older OMAP-specific
ones.

This is all fairly brainless/obvious stuff.  Probably the most interesting
bit is to observe that the omap-keypad code seems to now have a portable
core that could work with non-OMAP matrix keypads.  (That would improve
with hardware IRQ debouncing enabled, of course...)

The functions that write the OOB info (on hardware ECC only) use the 
HW_SYNDROME method.

This is not correct : the start position is "pos = eccsize + chunk" and 
should be eccsize. So, the standard (nand_write_oob_std) function should 
be used. This patch corrects this by using NAND_ECC_HW instead of 
NAND_ECC_HW_SYNDROME.

This has only been tested on small pages nand flash.
(if anyone can test it on large pages that would be great).

This patch extends the FSL UPM NAND driver from Anton Vorontsov to
support hardware which does not have the R/B pin of the NAND chip
connected, like the TQM8548 module:

- The OF_GPIO dependency has been removed from the Kconfig option
  because GPIO is not needed. The relevant gpio_* function are then
  stubbed out in <linux/gpio.h>.

- It re-introduces the chip-delay property to define an appropriate
  maximum delay time (tR) required for read operations. The binding
  will be documented in a separate patch.

- Get rid of fsl,wait-pattern and fsl,wait-write. I think this isn't
  chip-specific, and we should always do waits. I saw one board that
  didn't need fsl,wait-pattern, but I assume this was the exception
  that proves the rule;
- Get rid of chip-delay. Today there are no users for this, and if
  anyone really need this they should push the OF bindings beforehand;
- Now flash chips should be child nodes of the FSL UPM NAND controller;
- Implement OF partition parsing.

This patch moves the exported datastructures from the pxa3xx_nand.c driver
into the <mach/pxa3xx_nand.h> header. This is a plain movement without
any modification of the attributes.

This is the first one of a set of patches which:

 * allows to specify used NAND flash in the platform code and allows to turn
   off the old way to specify NAND characteristics in the driver.  This way did
   not worked well as these characteristics depend on the platform and can not be
   derived from NAND id alone.

   E.g.  some NAND chips share the same ID (e.g.  K9K8G08U0A and K9NBG08U5A) but
   have different timings (which are written in the common driver currently and
   must be modified there).

 * adds 'const' annotations at various places

Further patches will be sent to the mtd-list.

This patch for nand_ecc.c fixes three issues

- fix code so it also works on big endian architectures
- added a printk in case of an uncorrectable ecc error
- strengthen the test for correctable errors (decreasing the chance
  that multiple bit faults by accident will be seen as correctable)

Note: the big endian code is only tested in a testbed (running on big endian
hardware) as I cannot rebuild and test a big endian kernel at the moment.
However the only thing that can go wrong is if <asm/byteorder.h> does not
give __BIG_ENDIAN in that case. In my eyes very unlikely.
