Merge branch 'master' of git://git.denx.de/u-boot-nand-flash
* 'master' of git://git.denx.de/u-boot-nand-flash:
PPC: Fix socrates NAND problem
PPC: Fix fsl_upm.c by renaming nand handling functions
NAND: Make page, erase, oob size available via cmd_nand
mtd: eLBC NAND: remove elbc_fcm_ctrl->oob_poi
NAND: Add -y option to nand scrub command
NAND: Add nand read.raw and write.raw commands
NAND: Really ignore bad blocks when scrubbing
spl, nand: add 4bit HW ecc oob first nand_read_page function
mxc_nand: fix a problem writing more than 32MB
mxc_nand: fixed some typos (cosmetic)
nand: increase chip_delay in mv kirkwood nand driver
