2012-09-10NAND: MXS: include common.h first so cache.h is included in correct orderTom Warren
With Simon Glass's include/nand.h alignment changes, some mxs builds were generating errors. Fix is to ensure asm/cache.h is included before linux/mtd/nand.h. Moving common.h to top of include list does that. Signed-off-by: Tom Warren <twarren@nvidia.com> Acked-by: Simon Glass <sjg@chromium.org> Acked-by: Marek Vasut <marex@denx.de>

2012-09-03cfi: Make the flash erase and write operations abortableJoe Hershberger
Check for ctrlc() in operations that take time and loop over the flash addresses. In netconsole, tstc() is expensive. Only check once in a while to not slow down the operation significantly. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Signed-off-by: Stefan Roese <sr@denx.de>
2012-09-03cfi: Check for blank before eraseJoe Hershberger

2012-09-01at91: atmel_nand: Update driver to support Programmable Multibit ECC controllerWu, Josh
The Programmable Multibit ECC (PMECC) controller is a programmable binary BCH(Bose, Chaudhuri and Hocquenghem) encoder and decoder. This controller can be used to support both SLC and MLC NAND Flash devices. It supports to generate ECC to correct 2, 4, 8, 12 or 24 bits of error per sector of data. To use PMECC in this driver, the user needs to set the PMECC correction capability, the sector size and ROM lookup table offsets in board config file. This driver is ported from Linux kernel atmel_nand PMECC patch. The main difference is in this version it uses registers structure access hardware instead of using macros. It is tested in 9x5 serial boards. Signed-off-by: Josh Wu <josh.wu@atmel.com> [rebase] Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>

2012-09-01arm: omap: Fix switching back to nandecc sw.Jeroen Hofstee
Orjan Friberg wrote at [1]: "For the beagleboard, ecc.size is not explicitly set when doing 'nandecc sw'. If it's not set for the NAND_ECC_SOFT case in nand_scan_tail, it's set to 256 bytes. When doing 'nandecc hw', ecc.size is set to 512 bytes. Hence, when changing back to 'nandecc sw' ecc.size remains at 512 bytes and suddenly the format has changed." No patch has been submitted and the issue was still present. This patch adds the mentioned solution. Tested on a tam3517 board.

Commit a4ed3b6 "sf: inline data constants" modified winbond.c's page_size from 256 to 4096.

commit 54652991 Work around bug in Numonyx P33/P30 256-Mbit 65nm flash chips fixes a problem for Numonyx P33/P30 flashes for 256-Mbit, but this leads to problems for smaller versions of this chip e.g. the 32Mbit version with deviceid 0x16 on mgcoge. So move the code for this work around to an own function and check previously manufacturer id and device id to not break other flashes which don't need this work around.

Analysis of the flash drivers shows that they all use 0x20 if the erase size is 4KiB, or 0xd8 if it's larger. So with this info in hand, we can unify all the erase functionality in one place. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-03-04sf: inline data constantsMike Frysinger
