This patch contains a few changes for the sh_flctl driver:
- not sh7723-only driver - get rid of kconfig dependency
- use dev_err() instead of printk()
- use __devinit and __devexit for probe()/remove()
- fix probe() return values

This is a device driver for the NAND flash controller found on the various
DaVinci family chips. It handles up to four SoC chipselects, and some
flavors of secondary chipselect (e.g. based on upper bits of the address
bus) as used with some multichip packages. (Including the 2 GiB chips
used on some TI devel boards.)
The 1-bit ECC hardware is supported (3 bytes ECC per 512 bytes data); but
not yet the newer 4-bit ECC (10 bytes ECC per 512 bytes data), as
available on chips like the DM355 or OMAP-L137 and needed with the more
error-prone MLC NAND chips.
This is a cleaned-up version of code that's been in use for several years
now; sanity checked with the new drivers/mtd/tests.

The current ndfc driver only compiles under arch/ppc. This arch was
removed from the kernel. I notice the event entry for the ndfc in
Kconfig has been removed in 2.6.28.
This patch converts the ndfc to a proper OF (OpenFirmware) driver. I
can give a working example of the DTS if needed.
The patch has been in production use on the PIKA Warp Appliance and is
in use by others. The Warp basically boots from NAND, so the ndfc driver
is very important to us.

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.

This is preliminary since:
1. It supports only _one_ chip select at the moment. As there is no
existing platforms available using two chip selects of the NAND
controller, it shall really not include code for supporting the
2nd chip select for now, as such code cannot be verified.
2. It resorts to the default and simpliest memory based badblock
table
3. Only limited types of nand flash are currently supported. Most
PXA3xx processors come with on-chip NAND flash dies, so there
isn't much flexibility for other types of NAND.
4. The NAND controller should be configured to detect the device's
ID, thus making it difficult to use nand_scan_ident() to assist
the detection process (though it's not impossible)
