Lots (nearly all) mtd drivers contain nearly the similar code that
calls parse_mtd_partitions, provides some platform-default values, if
parsing fails, and registers mtd device.
This is an aim to provide single implementation of this scenario:
mtd_device_parse_register() which will handle all this parsing and
defaults.

mtd: pxa3xx_nand: Fix blank page ECC mismatch
This bug was introduced in f8155a40 ("mtd: pxa3xx_nand: rework irq
logic") and causes the PXA3xx NAND controller fail to operate with NAND
flash that has empty pages. According to the comment in this block, the
hardware controller will report a double-bit error for empty pages,
which can and must be ignored.
This patch restores the original behaviour of the driver.

physmap_configure() and physmap_set_partitions() have no users in kernel.
Out of kernel users should have been converted to regular platform device
long ago. Drop support for this obsolete API.
It's a Ceiva/Polaroid PhotoMax Digital Picture Frame. Support for it was
commited before 2.6.12-rc2, current git contains no functional changes
since it's start. Driver containing MTD support for that board was
broken for some time already.
Currently atmel_nand driver used by AT91 and AVR32 calls a special callback
which return nand partition table and number of partitions. However in all
boards this callback returns just static data. So drop this callback and
make atmel_nand use partition table provided statically via platform_data.
