3.10-stable review patch. If anyone has any objections, please let me know.
------------------ From: Sekhar Nori <[email protected]> commit acd36357edc08649e85ff15dc4ed62353c912eff upstream. Starting with kernel v3.5, it is mandatory to specify ECC strength when using hardware ECC. Without this, kernel panics with a warning of the sort: Driver must set ecc.strength when using hardware ECC ------------[ cut here ]------------ kernel BUG at drivers/mtd/nand/nand_base.c:3519! Fix this by specifying ECC strength for the boards which were missing this.
