3.11.10.9 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Herve Codina <Herve.CODINA@xxxxxxxxx> commit 90445ff6241e2a13445310803e2efa606c61f276 upstream. Crash detected on sam5d35 and its pmecc nand ecc controller. The problem was a call to chip->ecc.hwctl from nand_write_subpage_hwecc (nand_base.c) when we write a sub page. chip->ecc.hwctl function is not set when we are using PMECC controller. As a workaround, set NAND_NO_SUBPAGE_WRITE for PMECC controller in order to disable sub page access in nand_write_page.
