3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Roger Quadros <redacted>

commit 775a9134f4398ca98a10af8cc3cf9b664017267f upstream.

3430LDP has NAND flash with 32 bytes OOB size which is sufficient to hold
BCH8 codes but the small page check introduced in
commit b491da7233d5 ("mtd: nand: omap: clean-up ecc layout for BCH ecc schemes")
considers anything below 64 bytes unsuitable for BCH4/8/16. There is another
bug in that code where it doesn't skip the check for OMAP_ECC_HAM1_CODE_SW.

Get rid of that small page check code as it is insufficient and redundant
because we are checking for OOB available bytes vs ecc layout before calling
nand_scan_tail().

Fixes: b491da7233d5 ("mtd: nand: omap: clean-up ecc layout for BCH ecc schemes")
