Changelog:
- Check raw mode flag for backward compatbility
- Fix membership name in bch geometry structure.
- Fix the previous implementation that may ruin the BBM
- Adapt raw page accesses to match the new raw_read/write implementation
The old raw access implementation (in GPMI driver) was considering that
data and OOB data were separated in their respective regions (the data
area and the OOB area of the page), which is not true.
They are actually interleaved this way:
METADATA + ((DATA + ECCBYTES) * N)
The new raw access implementation (in the GPMI driver) is hiding this
weird
layout to MTD users by exposing a more common layout:
DATA + METADATA + (N * ECCBYTES)
Here METADATA + (N * ECCBYTES) are exposed as if they were stored in the
OOB area.
Unfortunately kobs-ng rely on this weird layout when accessing the NAND
in raw mode.

Changelog:
- add new feature to read bch geometry setting from debugfs, it provides
the feasibility to support large oob NAND devices.

Use a different versioning schema based on package versioning
instead of BSP version. This way, if a new BSP version does
not bump this package, we can keep this package unchanged as well.
Changelog since 3.14.28-1.0.0_ga:
- Add fixes for maximum ecc strength for each platform.
- Add mx7 boot config support.
- Add i.MX 6UltraLite support.
- Join the ecc with real FCB data when not byte-aligned.
- Generalize the encode_bch_ecc function for different configurations.

Starting with Linux 4.4 headers, mtd-user.h isn't including stdint.h any
more which breaks the build.

[Thomas:
- fix minor typo in the patch description
- add reference to the autobuilder failure, as suggested by Baruch.]
