2013-05-31mtd: resync with Linux-3.7.1Sergey Lapin
This patch is essentially an update of u-boot MTD subsystem to the state of Linux-3.7.1 with exclusion of some bits: - the update is concentrated on NAND, no onenand or CFI/NOR/SPI flashes interfaces are updated EXCEPT for API changes. - new large NAND chips support is there, though some updates have got in Linux-3.8.-rc1, (which will follow on top of this patch). To produce this update I used tag v3.7.1 of linux-stable repository. The update was made using application of relevant patches, with changes relevant to U-Boot-only stuff sticked together to keep bisectability. Then all changes were grouped together to this patch.

2013-04-01Consolidate bool typeYork Sun
'bool' is defined in random places. This patch consolidates them into a single header file include/linux/types.h, using stdbool.h introduced in C99. All other #define, typedef and enum are removed. They are all consistent with true = 1, false = 0. Replace FALSE, False with false. Replace TRUE, True with true. Skip *.py, *.php, lib/* files. Signed-off-by: York Sun <yorksun@freescale.com>
2012-11-26nand: Move the sub-page read support enable to a flagJoe Hershberger
Use a flag instead of a hard-coded macro so that sub-page reads can be enabled in other cases (such as on-die ecc). This is the same as a5ff4f102937a3492bca4a9ff0c341d78813414c in Linux Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>

2012-09-17mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driverMarek Vasut
This is based on Linux kernel -next: commit 14f44abf1dafc20ba42ce8616a8fc8fbd1b3712b Author: Brian Norris <computersforpeace@gmail.com> Date: Fri Jul 13 09:28:24 2012 -0700 mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driver The NAND_CHIPOPTIONS_MSK has limited utility and is causing real bugs. It silently masks off at least one flag that might be set by the driver (NAND_NO_SUBPAGE_WRITE). This breaks the GPMI NAND driver and possibly others. Really, as long as driver writers exercise a small amount of care with NAND_* options, this mask is not necessary at all; it was only here to prevent certain options from accidentally being set by the driver. But the original thought turns out to be a bad idea occasionally. Thus, kill it. Note, this patch fixes some major gpmi-nand breakage.

2011-04-01NAND: add support for reading ONFI page tableFlorian Fainelli
This patch adds support for reading an ONFI page parameter from a NAND device supporting it. If this is the case, struct nand_chip onfi_version member contains the supported ONFI version, 0 otherwise. This allows NAND drivers past nand_scan_ident to set the best timings for the NAND chip.

2009-08-26MTD:NAND: ADD new ECC mode NAND_ECC_HW_OOB_FIRSTSandeep Paulraj
This patch adds the new mode NAND_ECC_HW_OOB_FIRST in the nand code to support 4-bit ECC on TI DaVinci devices with large page (up to 2K) NAND chips. This ECC mode is similar to NAND_ECC_HW, with the exception of read_page API that first reads the OOB area, reads the data in chunks, feeds the ECC from OOB area to the ECC hw engine and perform any correction on the data as per the ECC status reported by the engine.

This patch adds a new "page" parameter to all NAND read_page/read_page_raw APIs. The read_page API for the new mode ECC_HW_OOB_FIRST requires the page information to send the READOOB command and read the OOB area before the data area.

2009-01-23NAND: rename NAND_MAX_CHIPS to CONFIG_SYS_NAND_MAX_CHIPSWolfgang Grandegger
This patch renames NAND_MAX_CHIPS to CONFIG_SYS_NAND_MAX_CHIPS and changes the default from 8 to 1 for the legacy and the new MTD NAND layer. This allows to remove all NAND_MAX_CHIPS definitions in the board config files because none of the boards use multi chip support (NAND_MAX_CHIPS > 1) so far. The bamboo and the DU440 define #define NAND_MAX_CHIPS CONFIG_SYS_MAX_NAND_DEVICE but that's bogus and did not work anyhow.

2008-10-29NAND: sync with 2.6.27Scott Wood
This brings the core NAND code up to date with the Linux kernel. Since there were several drivers in Linux as of the last update that are not in u-boot, I'm not bringing over new drivers that have been added since in the absence of an interested party. I did not update OneNAND since it was recently synced by Kyungmin Park, and I'm not sure exactly what the common ancestor is. Signed-off-by: Scott Wood <scottwood@freescale.com>

2008-08-12NAND: Scan bad blocks lazily.Ilya Yanok

2008-08-12Update MTD to that of Linux 2.6.22.1William Juul
A lot changed in the Linux MTD code, since it was last ported from Linux to U-Boot. This patch takes U-Boot NAND support to the level of Linux 2.6.22.1 and will enable support for very large NAND devices (4KB pages) and ease the compatibility between U-Boot and Linux filesystems. This patch is tested on two custom boards with PPC and ARM processors running YAFFS in U-Boot and Linux using gcc-4.1.2 cross compilers. MAKEALL ppc/arm has some issues: * DOC/OneNand/nand_spl is not building (I have not tried porting these parts, and since I do not have any HW and I am not familiar with this code/HW I think its best left to someone else.) Except for the issues mentioned above, I have ported all drivers necessary to run MAKEALL ppc/arm without errors and warnings. Many drivers were trivial to port, but some were not so trivial. The following drivers must be examined carefully and maybe rewritten to some degree: cpu/ppc4xx/ndfc.c cpu/arm926ejs/davinci/nand.c board/delta/nand.c board/zylonite/nand.c Signed-off-by: William Juul <william.juul@tandberg.com> Signed-off-by: Stig Olsen <stig.olsen@tandberg.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
