* git://git.infradead.org/mtd-2.6: (69 commits) Revert "[MTD] m25p80.c code cleanup" [MTD] [NAND] GPIO driver depends on ARM... for now. [MTD] [NAND] sh_flctl: fix compile error [MTD] [NOR] AT49BV6416 has swapped erase regions [MTD] [NAND] GPIO NAND flash driver [MTD] cmdlineparts documentation change - explain where mtd-id comes from [MTD] cfi_cmdset_0002.c: Add Macronix CFI V1.0 TopBottom detection [MTD] [NAND] Fix compilation warnings in drivers/mtd/nand/cs553x_nand.c [JFFS2] Write buffer offset adjustment for NOR-ECC (Sibley) flash [MTD] mtdoops: Fix a bug where block may not be erased [MTD] mtdoops: Add a magic number to logged kernel oops [MTD] mtdoops: Fix an off by one error [JFFS2] Correct parameter names of jffs2_compress() in comments [MTD] [NAND] sh_flctl: add support for Renesas SuperH FLCTL [MTD] [NAND] Bug on atmel_nand HW ECC : OOB info not correctly written [MTD] [MAPS] Remove unused variable after ROM API cleanup. [MTD] m25p80.c extended jedec support (v2) [MTD] remove unused mtd parameter in of_mtd_parse_partitions() [MTD] [NAND] remove dead Kconfig associated with !CONFIG_PPC_MERGE [MTD] [NAND] driver extension to support NAND on TQM85xx modules ...
