MFC r260092, r260093, r260121, r260180,

Allow AT91_MCI_ALLOW_OVERCLOCK to be an option in kernel config files.

Set the SoC name for the atmelbus name.

Add support for Samsung K9F2G08U0A (256MiB SLC) NAND

Comment updates.

MFC r257892, r258196, r258197, r258199, r258200, r258201, r258202:

Add ONFI signature check.

Add Micron chip found in Freescale Vybrid Family Phytec COSMIC board.

The vendor specified field is 88 bytes, not 8 bytes.

Update the onfi_params struct to ONFI revision 3.2 (06 12 2013).

Search for and validate the ONFI params as specified in the standard.

ONFI parameters are little-endian, hence we must take care to convert them
to native endianness. We must also pay attention to unaligned accesses.

Rework the routine that returns a pointer to the table of software ECC
byte positions within the OOB area to support chips with unusual OOB
sizes such as 218 or 224 bytes.

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

Import work done under project/nand (@235533) into head.

The NAND Flash environment consists of several distinct components:
- NAND framework (drivers harness for NAND controllers and NAND chips)
- NAND simulator (NANDsim)
- NAND file system (NAND FS)
- Companion tools and utilities
- Documentation (manual pages)

This work is still experimental. Please use with caution.
