commit dfe64e2c89731a3f9950d7acd8681b68df2bae03 Author: Sergey Lapin slapin@ossfans.org Date: Mon Jan 14 03:46:50 2013 +0000
mtd: resync with Linux-3.7.1
modified onenand_block_markbad to call mtd_block_markbad, but as _block_markbad function pointer used by mtd_block_markbad to do actual job is by default pointing back to onenand_block_markbad there is no way this function ever finishes its job. Fix it by changing function body according current (4.12-rc6) linux implementation. Tested on IGEPv2 board with Muxed OneNAND(DDP) 512MB containing several unerasable blocks this function marked bad.
