* nand: Remove CONFIG_MTD_NAND_VERIFY_WRITEPeter Tyser2015-03-30-18/+0
| | | | | | | | | The CONFIG_MTD_NAND_VERIFY_WRITE has been removed from Linux for some time and a more generic method of NAND verification now exists in U-Boot. Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Tested-by: Heiko Schocher <hs@denx.de> Acked-by: Heiko Schocher <hs@denx.de>
* mtd, ubi, ubifs: resync with Linux-3.14Heiko Schocher2014-08-25-0/+4
| | | | | | | | | | | | | | | | | | | | resync ubi subsystem with linux: commit 455c6fdbd219161bd09b1165f11699d6d73de11c Author: Linus Torvalds <torvalds@linux-foundation.org> Date: Sun Mar 30 20:40:15 2014 -0700 Linux 3.14 A nice side effect of this, is we introduce UBI Fastmap support to U-Boot.

* ppc4xx: Remove 4xx NAND booting supportStefan Roese2014-03-07-13/+0
| | | | | | | | | | | | | | | | | As ppc4xx currently only supports the deprecated nand_spl infrastructure and nobody seems to have time / resources to port this over to the newer SPL infrastructure, lets remove NAND booting completely. This should not affect the "normal", non NAND-booting ppc4xx platforms that are currently supported.

* mtd: resync with Linux-3.7.1Sergey Lapin2013-05-31-0/+1
| | | | | | | | | | | | | | | | | | | | | | 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.

* mtd: nand: Introduce CONFIG_SYS_NAND_BUSWIDTH_16BITFabio Estevam2013-04-12-2/+2
| | | | | | | | | | | | Introduce CONFIG_SYS_NAND_BUSWIDTH_16BIT option so that other NAND controller drivers could use it when a 16-bit NAND is deployed. drivers/mtd/nand/ndfc has CONFIG_SYS_NDFC_16BIT, so just rename it, so that other NAND drivers could reuse the same symbol.

* NAND: Add 16bit NAND support for the NDFCAlex Waterman2011-07-01-4/+29
| | | | | | | | | | | | | | | | | | | This patch adds support for 16 bit NAND devices attached to the NDFC on ppc4xx processors. Two config entries were added: CONFIG_SYS_NDFC_16 - Setting this tells the NDFC that a 16 bit device is attached. CONFIG_SYS_NDFC_EBC0_CFG - This is for the External Bus Controller configuration register. Also, a new ndfc_read_byte() function was added which does not first convert the data to little endian. The NAND SPL was also modified to do 16bit bad block testing when a 16 bit chip is being used. Signed-off-by: Alex Waterman <awaterman@dawning.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
* ppc4xx/NAND: Reduce size of NAND SPL imageStefan Roese2010-11-27-2/+2

* ppc4xx: Move ppc4xx headers to powerpc include directoryStefan Roese2010-09-23-1/+1
| | | | | | | | | This patch moves some ppc4xx related headers from the common include directory (include/) to the powerpc specific one (arch/powerpc/include/asm/). This way to common include directory is not so cluttered with files. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Big cleanup of PPC4xx definesStefan Roese2009-09-11-2/+2
| | | | | | | | | | | | | | | | This patch cleans up multiple issues of the 4xx register (mostly DCR, SDR, CPR, etc) definitions: - Change lower case defines to upper case (plb4_acr -> PLB4_ACR) - Change the defines to better match the names from the user's manuals (e.g. cprpllc -> CPR0_PLLC) - Removal of some unused defines Please test this patch intensive on your PPC4xx platform. Even though I tried not to break anything and tested successfully on multiple 4xx AMCC platforms, testing on custom platforms is recommended. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Fix ECC Correction bug with SMC ordering for NDFC driverFeng Kan2009-08-25-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Fix ECC Correction bug where the byte offset location were double flipped causing correction routine to toggle the wrong byte location in the ECC segment. The ndfc_calculate_ecc routine change the order of getting the ECC code. /* The NDFC uses Smart Media (SMC) bytes order */ ecc_code[0] = p[2]; ecc_code[1] = p[1]; ecc_code[2] = p[3]; But in the Correction algorithm when calculating the byte offset location, the s1 is used as the upper part of the address. Which again reverse the order making the final byte offset address location incorrect. byteoffs = (s1 << 0) & 0x80; . . byteoffs |= (s0 >> 4) & 0x08; The order is change to read it in straight and let the correction function to revert it to SMC order.
