* 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>

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | 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.
