Merge git://git.infradead.org/mtd-2.6
* git://git.infradead.org/mtd-2.6: (21 commits) [MTD] [CHIPS] Remove MTD_OBSOLETE_CHIPS (jedec, amd_flash, sharp) [MTD] Delete allegedly obsolete "bank_size" field of mtd_info. [MTD] Remove unnecessary user space check from mtd.h. [MTD] [MAPS] Remove flash maps for no longer supported 405LP boards [MTD] [MAPS] Fix missing printk() parameter in physmap_of.c MTD driver [MTD] [NAND] platform NAND driver: add driver [MTD] [NAND] platform NAND driver: update header [JFFS2] Simplify and clean up jffs2_add_tn_to_tree() some more. [JFFS2] Remove another bogus optimisation in jffs2_add_tn_to_tree() [JFFS2] Remove broken insert_point optimisation in jffs2_add_tn_to_tree() [JFFS2] Remember to calculate overlap on nodes which replace older nodes [JFFS2] Don't advance c->wbuf_ofs to next eraseblock after wbuf flush [MTD] [NAND] at91_nand.c: CMDLINE_PARTS support [MTD] [NAND] Tidy up handling of page number in nand_block_bad() [MTD] block2mtd_paramline[] mustn't be __initdata [MTD] [NAND] Support multiple chips in CAFÉ driver [MTD] [NAND] Rename cafe.c to cafe_nand.c and remove the multi-obj magic [MTD] [NAND] Use rslib for CAFÉ ECC [RSLIB] Support non-canonical GF representations [JFFS2] Remove dead file histo_mips.h ...
