Which was not possible before, because ecc_mode was arbitrarily set to NAND_ECC_SOFT.

2014-03-03	ad22ad3 Browse files » mtd: nand: atmel pmecc: disable subpage writes ... I am using an sam5d35 and its pmecc nand ecc controller. In barebox, using similar atmel_nand.c the system crashes. 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, i set NAND_NO_SUBPAGE_WRITE for PMECC controller in order to disable sub page access in nand_write_page. I think we can have the same problem in Linux. I do not performed subpage nand writes from Linux but i made the following patch according to my Barebox defect.

It is synchronized as best as we can get: - locks removed - The splitting in different files we had to better support different features has been dropped. Instead this is now done mostly with the use of __maybe_unused Some barebox adjustments are forward ported, like: - Allow partial page writes - Optionally allow to erase bad blocks - check for all_ff before writing a page Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 23 Jul 2013
