* ENGR00231891-2 gpmi: fix the 4k page size limitHuang Shijie2012-10-31-2/+2
| | | | | | | We may use the 8K page nand now. So expand the page size from 4k to 8K. Also expand the oobsize to 1K size. Signed-off-by: Huang Shijie <b32955@freescale.com>

* NAND: Update to support 64 bit device sizeSandeep Paulraj2010-12-03-1/+1
| | | | | | | | This patch adds support for NANDs greater than 2 GB. Patch is based on the MTD NAND driver in the kernel. Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
* ENGR00118789 Uboot:Update NAND scan scheme to support new nand typeJason2009-12-08-0/+2
| | | | | | | | Update NAND scan scheme to support new nand type. With this patch uboot can support new NAND flash on mx25/mx35 board while compatible with old NAND on old boards. Signed-off-by: Jason Liu <r64343@freescale.com>

* nand: Change NAND_MAX_OOBSIZE to 218 as needed for some 4k page devicesStefan Roese2009-07-16-1/+1
| | | | | | | | | This is needed for the MPC512x NAND driver (fsl_nfc_nand.c) which already defines such a 4k plus 218 bytes ECC layout. Signed-off-by: Stefan Roese <sr@denx.de> Cc: Scott Wood <scottwood@freescale.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
* NAND: rename NAND_MAX_CHIPS to CONFIG_SYS_NAND_MAX_CHIPSWolfgang Grandegger2009-01-23-9/+0
| | | | | | | | | | | | | | | | 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.

* NAND: Allow NAND and OneNAND to coexistAlessandro Rubini2008-10-31-69/+1
| | | | | | | | | | This removes in nand.h code that is verbatim duplicated from bbm.h, including directly bbm.h in nand.h. The previous state of affairs prevented compiling code for a board hosting both NAND and OneNAND chips.

* NAND: sync with 2.6.27Scott Wood2008-10-29-3/+9
| | | | | | | | | | | | | 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>
* Fix OneNAND build breakKyungmin Park2008-08-13-15/+1
| | | | | | | | | Since page size field is changed from oobblock to writesize. But OneNAND is not updated. - fix bufferram management at erase operation This patch includes the NAND/OneNAND state filed too.

* NAND: Scan bad blocks lazily.Ilya Yanok2008-08-12-0/+2
| | | | | | | | | | Rather than scanning on boot, scan upon the first attempt to check the badness of a block. This speeds up boot when not using NAND, and reduces the likelihood of needing to reflash via JTAG if NAND becomes nonfunctional.

* Update MTD to that of Linux 2.6.22.1William Juul2008-08-12-144/+306
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
