[PATCH v4 0/8] sh_flctl hardware ECC mode cleanup

[Bastian Hecht <hechtb@googlemail.com>]

changelog v4:

  - removed arch/arm related patches
  - rebased on current l2-mtd.git
  - fixed some compiler warnings
	- patch 2: use "int irq" when removing irq binding in error case to fix smatch breakage
	- patch 7 and 8: just directly use the void __iomem pointer instead of the unprecise void pointer to fix sparse breakage

changelog v3:

Just a rebase on current l2-mtd.git.

changelog v2:
  - extract the iounmap calls from patch "Add support for error IRQ" into a new patch.
  - swapped patches "Add support for error IRQ" and "Add error IRQ resource"
  - corrected an indentation mistake

This series cleans up the flctl when run in hardware ecc mode. The first 2 patches make sure we catch all errors that result from hardware transmission. The other patches handle how the ecc is layed out, correct some code to write and read it and make sure we propagate the statistics about errors/repairs to the nand base.
