Pull MTD updates from Richard Weinberger:
"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"
