| * NAND: Update nand_ecc.c to latest Linux versionStefan Roese2007-06-01-136/+92
| | | | | | | | | | | | | | | | | | This patch updates the nand_ecc code to the latest Linux version. The main reason for this is the more compact code. This makes it possible to include the ECC code into the NAND bootloader image (NAND_SPL) for PPC4xx. Signed-off-by: Stefan Roese <sr@denx.de>
* | NAND: Wrong calculation of page number in nand_block_bad()Thomas Knobloch2007-05-05-5/+5
|/ | | | | | | | | | | In case that there is no memory based bad block table available the function nand_block_checkbad() in drivers/mtd/nand/nand_base.c will call nand_block_bad() directly. When parameter 'getchip' is set to zero, nand_block_bad() will not right shift the offset to calculate the correct page number.

* [PATCH] nand: Fix problem with oobsize calculationStefan Roese2007-01-05-1/+1
| | | | | | | | | | | | | | | | | | Here the description from Brian Brelsford <Brian_Brelsford@dell.com>: The Hynix part returns a 0x1d in the 4th ID byte. The Samsung part returns a 0x15. In the code fragment below bits [1:0] determine the page size, it is ANDed via "(extid & 0x3)" then shifted out. The next field is also ANDed with 0x3. However this is a one bit field as defined in the Hynix and Samsung parts in the 4th ID byte that determins the oobsize, not a two bit field. It works on Samsung as bits[3:2] are 01. However for the Hynix there is a 11 in these two bits, so the oob size gets messed up. I checked the correct linux code and the suggested fix from Brian is also available in the linux nand mtd driver. Signed-off-by: Stefan Roese <sr@denx.de>

| * | | NAND Flash verify across block boundariesNick Spence2006-11-03-0/+1
| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch addresses a problem when CONFIG_MTD_NAND_VERIFY_WRITE is defined and the write crosses a block boundary. The pointer to the verification buffer (bufstart) is not being updated to reflect the starting of the new block so the verification of the second block fails. CHANGELOG: * Fix NAND FLASH page verification across block boundaries

* | | [PATCH] nand_wait() timeout fixesStefan Roese2006-11-27-4/+4
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | Two fixes for the nand_wait() function in drivers/nand/nand_base.c: 1. Use correct timeouts. The original timeouts in Linux source are 400ms and 20ms not 40s and 20s 2. Return correct error value in case of timeout. 0 is interpreted as OK.

* Add support for a saving build objects in a separate directory.Marian Balakowicz2006-09-01-6/+35
| | | | | | | | | | | | | | | | | | | | | Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory.

|/ | | | | | | | | * For READ_STATUS and READID commands always 8 bytes need to be read from NDDB. Otherwise they stay there and get send to flash as the first data word when writing. * In nand_base.c the oob variable is not reset so this->oob_buf is overwritten what eventually screws up the bad block descriptor table.
