nand: Fix problem with ECC ordering for PPC4xx NDFC platforms

2009-05-23T10:51:39Z

This patch enables Smart Media (SMC) ECC byte ordering which is used on the PPC4xx NAND FLASH controller (NDFC). Without this patch we have incompatible ECC byte ordering to the Linux kernel NDFC driver. Signed-off-by: Stefan Roese Acked-by: Scott Wood

mtd: nand/onenand: Register mtd device upon device scanning

2009-04-27T23:15:38Z

With this patch the NAND and OneNAND devices are registered in the MTD subsystem and can then be referenced by the mtdcore code (e.g. get_mtd_device_nm()). This is needed for the new "ubi part" command syntax without the flash type parameter (nor|nand|onenand). Signed-off-by: Stefan Roese

mtd: nand: Include linux/mtd/partitions.h in nand_base.h

2009-04-27T23:15:37Z

This patch removes this compilation warning when CONFIG_MTD_PARTITIONS is defined: nand_base.c: In function 'nand_release': nand_base.c:2922: warning: implicit declaration of function 'del_mtd_partitions' Signed-off-by: Stefan Roese

Blackfin: nand: flush peripheral before polling it

2009-04-06T21:37:37Z

We need to make sure the data written to the nand flash controller makes it there before we start polling its status register. Otherwise, we may get stale data and return before the controller is actually ready. Signed-off-by: Graf Yang Signed-off-by: Mike Frysinger Acked-by: Scott Wood

Add wait flags to support board/chip specific delays

2009-03-23T20:53:40Z

The NAND flash on the TQM8548_BE modules requires a short delay after running the UPM pattern like the MPC8360ERDK board does. The TQM8548_BE requires a further short delay after writing out a buffer. Normally the R/B pin should be checked, but it's not connected on the TQM8548_BE. The corresponding Linux FSL UPM driver uses similar delay points at the same locations. To manage these extra delays in a more general way, I introduced the "wait_flags" field allowing the board-specific driver to specify various types of extra delay.

Add support for TQM-specific chip select logic to FSL-UPM

2009-03-23T20:53:39Z

For the NAND chips on the TQM8548 modules, a special chip-select logic is used. It uses dedicated address lines to be set via UPM machine address register (mar). This patch adds such support to the FSL-UPM driver. Signed-off-by: Wolfgang Grandegger Signed-off-by: Scott Wood

Add multi chip support to the FSL-UPM driver

2009-03-23T20:53:38Z

This patch adds support for multi-chip NAND devices to the FSL-UPM driver. The "dev_ready" callback of the "struct fsl_upm_nand" is now called with the argument "chip_nr" to allow testing the proper chip select line. The NAND support of the MPC8360ERDK is updated as well. No other boards are currently using the FSL UPM driver. Signed-off-by: Wolfgang Grandegger Signed-off-by: Scott Wood
