General changes:
* Unconfuse get_unmapped_area and point/unpoint driver methods
* New partition parser: sharpslpart
* Kill GENERIC_IO
* Various fixes
NAND changes:
* Add a flag to mark NANDs that require 3 address cycles to encode a
page address
* Set a default ECC/free layout when NAND_ECC_NONE is requested
* Fix a bug in panic_nand_write()
* Another batch of cleanups for the denali driver
* Fix PM support in the atmel driver
* Remove support for platform data in the omap driver
* Fix subpage write in the omap driver
* Fix irq handling in the mtk driver
* Change link order of mtk_ecc and mtk_nand drivers to speed up boot
time
* Change log level of ECC error messages in the mxc driver
* Patch the pxa3xx driver to support Armada 8k platforms
* Add BAM DMA support to the qcom driver
* Convert gpio-nand to the GPIO desc API
* Fix ECC handling in the mt29f driver
SPI-NOR changes:
* Introduce system power management support
* New mechanism to select the proper .quad_enable() hook by JEDEC ID,
when needed, instead of only by manufacturer ID
* Add support to new memory parts from Gigadevice, Winbond, Macronix and
Everspin
* Maintainance for Cadence, Intel, Mediatek and STM32 drivers
