* [MTD] [NAND] rename at91_nand -> atmel_nand: file names and KconfigHåvard Skinnemoen2008-06-071-592/+0
| | | | | | | | | | | | The AT91 NAND driver needs just a few tiny modifications to work on AVR32 as well. Rename it atmel_nand to reflect this. Also move the ECC register definitions into drivers/mtd/nand since they are only useful to the atmel_nand driver, and get rid of the useless filename at the top of each file.

* [MTD] [NAND] at91_nand: Convert to generic GPIO APIHåvard Skinnemoen2008-06-071-7/+5
| | | | | | | | No point in using an AT91-specific GPIO API when the generic API works just as well. Signed-off-by: Håvard Skinnemoen <haavard.skinnemoen@atmel.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
* [MTD] [NAND] at91_nand: use at91_nand_{en,dis}able consistently.Atsushi Nemoto2008-04-261-21/+21
| | | | | | | | Use at91_nand_enable(), at91_nand_disable() to manipulate enable_pin. No functional changes. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
* [MTD] [NAND] at91_nand: control NCE signalAtsushi Nemoto2008-04-251-0/+6
| | | | | | | | | This driver did not control NCE signal during normal operations (only enable NCE on probing and disable NCE on removing). This patch make NCE signal inactive on idle state. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
* [MTD] [NAND] AT91 hardware ECC compile fix for at91sam9263 / at91sam9260Richard Genoud2008-04-251-1/+1
| | | | | | | | | | The sam926x docs allegedly don't list an "ECC_PARITY" field, and the header files in the upstream kernel don't have it either. Masking with it was useless anyway, so just remove it. Signed-off-by: Richard Genoud <richard.genoud@gmail.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
* [MTD] [NAND] Hardware ECC controller on at91sam9263 / at91sam9260Richard Genoud2008-04-231-5/+356
| | | | | | | | | | | | | This is a patch to use the hardware ECC controller of the AT91SAM9260 and AT91SAM9263 for the AT91 nand. On AT91 NAND, there's now a choice between ECC soft, ECC hard or no ECC (for debug). It has been tested on AT91SAM9263 with 8 bits large and small page NAND.

* [MTD] [NAND] fix platform driver hotplug/coldplugKay Sievers2008-04-221-0/+1
| | | | | | | | | | | | | | | Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable MTD NAND platform drivers, to re-enable auto loading. NOTE: at91_nand for some reason disallows modular builds. I'm assuming that's just an oversight that will be fixed.

* [MTD] NAND: Support for 16-bit bus-width on AT91.Andrew Victor2006-12-081-0/+3
| | | | | | | | | | | | Add support for 16-bit NAND bus-width for the AT91 NAND driver. The 16-bit NAND is found on the Atmel AT91SAM9260-EK and AT91SAM9261-EK boards.

* [MTD] NAND: AT91 NAND driverAndrew Victor2006-10-211-0/+220
This version only differs from version posted by Savin Zlobec (20 Jun 2006) in that the AT91RM9200-specific chip-select / bus setup code has been moved from the at91_nand.c driver into the processor-specific file.
