[U-Boot] [PATCH v3 0/8] mtd: vf610_nfc: various fixes and improvements

[Stefan Agner]

This patchset contains various improvements and enhancements to the
NAND flash controller found on Vybrid (vf610) and other Freescale
platforms. It's a merge and follow up of two patchset sent earlier:
- mtd: vf610_nfc: remove caching of page in page buffer
  http://lists.denx.de/pipermail/u-boot/2015-April/209817.html
- mtd: vf610_nfc: use in-band bad block table
  http://lists.denx.de/pipermail/u-boot/2015-April/209889.html

The patch "mtd: vf610_nfc: support subpage write" has been dropped
as discussed. As a further consequence, this patchset includes a
patch which changes the behaviour of the SEQIN command (patch 3).

- Patch 1 to 3 fix non-critical issues or undesirable behavior.
- Patch 4 enhances the driver with a page read function with reads
  the OOB area only and also simplifies vf610_nfc_read_buf.
- Patch 5 switches to in-band bad block table which is a prerequisit
  for 32-error correction (patch 7) on 64 byte OOB.
- Patch 6 converts the driver to be configureable through Kconfig.
- Patch 7 enhances driver configuration for 32-error correction.
- Patch 8 allows reading the ONFI parameter page.

The changes between 1-4 has been discussed on the mailinglist lately.

Changes since v2:
- Reverse parameter page (ONFI) byte order only on little endian
  architectures
- Rebased ontop of v2014.07-rc1, also considering new Vybrid board
  colibri_vf_defconfig
