* Remove unused NAND locking support
* Rename nand.h into rawnand.h (preparing support for spi NANDs)
* Use NAND_MAX_ID_LEN where appropriate
* Fix support for 20nm Hynix chips
* Fix support for Samsung and Hynix SLC NANDs
and the following driver changes:
* Various cleanup, improvements and fixes in the qcom driver
* Fixes for bugs detected by various static code analysis tools
* Fix mxc ooblayout definition
* Add a new part_parsers to tmio and sharpsl platform data in order to
define a custom list of partition parsers
* Request the reset line in exclusive mode in the sunxi driver
* Fix a build error in the orion-nand driver when compiled for ARMv4
* Allow 64-bit mvebu platforms to select the PXA3XX driver
