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
