* | driver/mtd/ifc: Read Status while programming NAND flashPrabhakar Kushwaha2013-11-13-5/+16
|/ | | | | | | | | | | | | | | | | as per controller description, "While programming a NAND flash, status read should never skipped. Because it may happen that a new command is issued to the NAND Flash, even when the device has not yet finished processing the previous request. This may result in unpredictable behaviour." IFC controller never polls for R/B signal after command send. It just return control to software. This behaviour may not occur with NAND flash access. because new commands are sent after polling R/B signal. But it may happen in scenario where GPCM-ASIC and NAND flash device are working simultaneously. Update the controller driver to take care of this requirement Signed-off-by: Prabhakar Kushwaha <prabhakar@freescale.com>

* mtd: resync with Linux-3.7.1Sergey Lapin2013-05-31-8/+12
| | | | | | | | | | | | | | | | | | | | | | 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.

* driver/mtd:IFC NAND:Initialise internal SRAM before any writePrabhakar Kushwaha2012-11-26-1/+61
| | | | | | | | | | | | | | | | IFC-1.1.0 uses 28nm techenology for SRAM. This tech has known limitaion for SRAM i.e. "byte select" is not supported. Hence Read Modify Write is implemented in IFC for any "system side write" into sram buffer. Reading an uninitialized memory results in ECC Error from sram wrapper. Hence we must initialize/prefill SRAM buffer by any data before writing anything in SRAM from system side. To initialize SRAM user can use "READID" NAND command with read bytes equal to SRAM size.

* mtd/nand:Fix wrong usage of is_blank() in fsl_ifc_run_commandPrabhakar Kushwaha2012-02-28-24/+28
| | | | | | | | | | | | | | Freescale IFC NAND Machine calculates ECC on 512byte sector and same is used in fsl_ifc_run_command() during ECC status verification. Also this sector is passed to is_blank() for blank checking. It is wrong at first place because is_blank()'s implementation checks for Page size and OOB area size. is_blank() should be called per page for main and OOB area verification. Variables name are redefined to avoid confusion between buffer and ecc sector.

* nand: Freescale Integrated Flash Controller NAND supportDipen Dudhat2011-09-29-0/+850
Add NAND support (including spl) on IFC, such as is found on the p1010. Note that using hardware ECC on IFC with small-page NAND (which is what comes on the p1010rdb reference board) means there will be insufficient OOB space for JFFS2, since IFC does not support 1-bit ECC. UBI should work, as it does not use OOB for anything but ECC. When hardware ECC is not enabled in CSOR, software ECC is now used.
