2014-03-12	3676454 Browse files » nand: mxs: Fix for calculating ecc strength on some types of NAND flash ... Was tested on NAND with {writesize=4096, oobsize=224} and {writesize=2048, oobsize=64}. This patch will not break any NAND that was working before. Implemented calculation way may be used for other NAND chips with writesize == 2048 but oobsize != 64.

	ca13a84 Browse files » ARM: MXS: introduce stmp device support ... MXS specific devices have some common infrastructure in the kernel known as STMP devices. We have the same in barebox, but with a mxs_ prefix instead of a stmp_ prefix. As some STMP devices are also found on i.MX6 move the common infrastructure out of MXS specific files and use the stmp_ prefix. This is done in preparation for i.MX6 NAND support.

	6689156 Browse files » mtd: nand: update to v3.11-rc1 ... This updates the NAND stuff to Linux-3.11-rc1. 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

2012-12-06	9711009 Browse files » mtd: nand: mxs: reset BCH earlier, too, to avoid NAND startup problems ... It could happen (1 out of 100 times) that NAND did not start up correctly after warm rebooting, so barebox could not find its environment or DMA timed out due to a stalled BCH. When resetting BCH together with GPMI, the issue could not be observed anymore. We probably need the consistent state already before sending commands to NAND.
