| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the integrated NAND flash controller of the TXx9 family. Once upon a time there were tx4925ndfmc and tx4938ndfmc driver. They were removed due to bitrot in 2005. This new driver is completely rewritten based on a driver in CELF patch archive.

| * [MTD] [NAND] davinci_nand driverDavid Brownell2009-03-201-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a device driver for the NAND flash controller found on the various DaVinci family chips. It handles up to four SoC chipselects, and some flavors of secondary chipselect (e.g. based on upper bits of the address bus) as used with some multichip packages. (Including the 2 GiB chips used on some TI devel boards.) The 1-bit ECC hardware is supported (3 bytes ECC per 512 bytes data); but not yet the newer 4-bit ECC (10 bytes ECC per 512 bytes data), as available on chips like the DM355 or OMAP-L137 and needed with the more error-prone MLC NAND chips. This is a cleaned-up version of code that's been in use for several years now; sanity checked with the new drivers/mtd/tests.

* [MTD] [NAND] ndfc driverSean MacLennan2009-01-051-0/+7
| | | | | | | | | | | | | | | | | The current ndfc driver only compiles under arch/ppc. This arch was removed from the kernel. I notice the event entry for the ndfc in Kconfig has been removed in 2.6.28. This patch converts the ndfc to a proper OF (OpenFirmware) driver. I can give a working example of the DTS if needed. The patch has been in production use on the PIKA Warp Appliance and is in use by others. The Warp basically boots from NAND, so the ndfc driver is very important to us.

* [MTD] [NAND] driver extension to support NAND on TQM85xx modulesWolfgang Grandegger2008-10-101-1/+1
| | | | | | | | | | | | | | | | | This patch extends the FSL UPM NAND driver from Anton Vorontsov to support hardware which does not have the R/B pin of the NAND chip connected, like the TQM8548 module: - The OF_GPIO dependency has been removed from the Kconfig option because GPIO is not needed. The relevant gpio_* function are then stubbed out in <linux/gpio.h>. - It re-introduces the chip-delay property to define an appropriate maximum delay time (tR) required for read operations. The binding will be documented in a separate patch. Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

* [MTD] [NAND] support for pxa3xxeric miao2008-04-221-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | This is preliminary since: 1. It supports only _one_ chip select at the moment. As there is no existing platforms available using two chip selects of the NAND controller, it shall really not include code for supporting the 2nd chip select for now, as such code cannot be verified. 2. It resorts to the default and simpliest memory based badblock table 3. Only limited types of nand flash are currently supported. Most PXA3xx processors come with on-chip NAND flash dies, so there isn't much flexibility for other types of NAND. 4. The NAND controller should be configured to detect the device's ID, thus making it difficult to use nand_scan_ident() to assist the detection process (though it's not impossible) TODO: fix all the above limitations of cuz :-) Signed-off-by: eric miao <eric.miao@marvell.com> Cc: Sergey Podstavin <spodstavin@ru.mvista.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
