* Fix regression in SMDK6400Simon Schwarz2011-12-06-26/+2
| | | | | | | | | | | | | | | | | | | s3c64xx.c implemented its own nand_read_byte, nand_write_buf and nand_read_buf functions. This provoked a regression when these functions were made public by patch 55f429bb39614a16b1bacc9a8bea9ac01a60bfc8. This deletes these duplicated functions from s3c64xx.c and adds the generic implementations in nand_base.c to the spl Makefile. It also adds -ffcuntion-sections and -gc-sections to the compilation flags of the SPL to avoid errors originating from unused functions in nand_base.c.

* | NAND: davinci: choose correct 1-bit h/w ECC regLaurence Withers2011-10-10-13/+13
|/ | | | | | | | | | | | | | | | | | | In nand_davinci_readecc(), select the correct NANDF<n>ECC register based on CONFIG_SYS_NAND_CS rather than hardcoding the choice of NANDF1ECC. This allows 1-bit hardware ECC to work with chip select other than CS2. Note this now matches the usage in nand_davinci_enable_hwecc(), which already had the correct handling, and allows refactoring to a single function encapsulating the register read. Without this fix, writing NAND pages to a chip not wired to CS2 would result in in the ECC calculation always returning FFFFFF for each 512-byte segment, and reading back a correctly written page (one with ECC intact) would always fail. With this fix, the ECC is written and verified correctly. Signed-off-by: Laurence Withers <lwithers@guralp.com> Signed-off-by: Scott Wood <scottwood@freescale.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | When writing 0x4000 to the unlockend_blkaddr register, large writes to a 2k page NAND sometimes fail. The current kernel driver writes 0xFFFF to this register for V2 of the nand controller. However on an i.MX31 this also fixes writes larger than 32MB. The datasheet is very unspecific, but (0x4000=16384)*2000 roughly fits the limits we're encountering with NAND writes. This problem might be NAND chip specific.

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.

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.

* NAND: rearrange ONFI revision checking, add ONFI 2.3Florian Fainelli2011-04-15-8/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch sync with Brian's patch on Linux in nand_flash_detect_onfi() commit b7b1a29d94c17e4341856381bccb4d17495bea60 Author: Brian Norris <computersforpeace@gmail.com> Date: Sun Dec 12 00:23:33 2010 -0800 mtd: nand: rearrange ONFI revision checking, add ONFI 2.3 In checking for the ONFI revision, the first conditional (for checking "unsupported" ONFI) seems unnecessary. All ONFI revisions should be backwards-compatible; even if this is not the case on some newer ONFI revision, it should simply fail the second version-checking if-else block (i.e., the bit-fields for 1.0, 2.0, etc. would not be set to 1). Thus, we move our "unsupported" condition after having checked each bit field. Also, it's simple enough to add a condition for ONFI revision 2.3. Note that this does *NOT* mean we handle all new features of ONFI versions above 1.0.

* atmel_nand: don't require CONFIG_SYS_NAND_ENABLE_PINmichael2011-04-01-0/+2
| | | | | | | | | | | | If NCE is hooked up to NCS3, we don't need to (and can't) explicitly set the state of the NCE pin. Instead, the controller asserts it automatically as part of a command/data access. Only "CE don't care"-type NAND chips can be used in this manner.

* NAND: add support for reading ONFI page tableFlorian Fainelli2011-04-01-49/+144
| | | | | | | | | | | | 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.
