In preparation of re-sync of mtd stack, we opt to move the current stack
slowly in order to have a more easy sync and test. We would like to
prepare uboot to support no-jedec and no-onfi compliant nand so we need
to clean up a bit the code we have now and upstream some of the support.
In this series we expect no functional change

Tested on:
        - imx6ull Micron MT29F2G08ABAGAH4

Michael Trimarchi (13):
  mtd: nand: Get rid of busw parameter
  mtd: nand: Store nand ID in struct nand_chip
  mtd: nand: Add manufacturer specific initialization/detection steps
  mtd: nand: Get rid of mtd variable in function calls
  mtd: nand: Export symbol nand_decode_ext_id
  mtd: nand: Move Samsung specific init/detection logic in
  mtd: nand: Move Hynix specific init/detection logic in nand_hynix.c
  mtd: nand: Move Toshiba specific init/detection logic in
  mtd: nand: Move Micron specific init logic in nand_micron.c
  mtd: nand: Move AMD/Spansion specific init/detection logic in
  mtd: nand: Move Macronix specific initialization in nand_macronix.c
  mtd: nand: toshiba: Retrieve ECC requirements from extended ID
  mtd: decommission the NAND museum
