* git://git.infradead.org/mtd-2.6: (67 commits) [MTD] [MAPS] Fix printk format warning in nettel.c [MTD] [NAND] add cmdline parsing (mtdparts=) support to cafe_nand [MTD] CFI: remove major/minor version check for command set 0x0002 [MTD] [NAND] ndfc driver [MTD] [TESTS] Fix some size_t printk format warnings [MTD] LPDDR Makefile and KConfig [MTD] LPDDR extended physmap driver to support LPDDR flash [MTD] LPDDR added new pfow_base parameter [MTD] LPDDR Command set driver [MTD] LPDDR PFOW definition [MTD] LPDDR QINFO records definitions [MTD] LPDDR qinfo probing. [MTD] [NAND] pxa3xx: convert from ns to clock ticks more accurately [MTD] [NAND] pxa3xx: fix non-page-aligned reads [MTD] [NAND] fix nandsim sched.h references [MTD] [NAND] alauda: use USB API functions rather than constants [MTD] struct device - replace bus_id with dev_name(), dev_set_name() [MTD] fix m25p80 64-bit divisions [MTD] fix dataflash 64-bit divisions [MTD] [NAND] Set the fsl elbc ECCM according the settings in bootloader. ... Fixed up trivial debug conflicts in drivers/mtd/devices/{m25p80.c,mtd_dataflash.c}
