* [MTD] [NAND] fsl_elbc_nand: workaround for hangs during nand writeAnton Vorontsov2008-04-22
| | | | | | | | | Using current driver elbc sometimes hangs during nand write. Reading back last byte helps though (thanks to Scott Wood for the idea).

* [MTD] [NAND] plat_nand: set mtd->nameHamish Moffatt2008-04-22
| | | | | | | | | | | | This patch sets mtd->name to the platform bus ID in the plat_nand driver, so that you can specify partitions readily with mtdparts=. Currently it relies on nand_base filling in the name from the device, which results in names like "NAND 256MiB 3,3V 8-bit", that you can't use with cmdlineparts.

* [MTD] [NAND] fsl_elbc_nand: fix mtd nameAnton Vorontsov2008-04-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently fsl_elbc_nand doesn't initialize mtd->name, and this causes nand_get_flash_type() to assign name that is equal to chip type, like this: root@b1:~# cat /proc/mtd dev: size erasesize name mtd0: 00800000 00010000 "fe000000.flash" mtd1: 02000000 00004000 "NAND 32MiB 3,3V 8-bit" mtd0 is physmap_of flash (normal name), and mtd1 is fsl_elbc_nand. Despite inconsistency, with mtd name like this specifying paritions from the kernel command line becomes a torture (though, I didn't tried and not sure if mtdparts= can handle spaces at all). Plus, this causes real bugs when multiple fsl_elbc_nand chips registered. With this patch applied fsl_elbc_nand chip will have proper name: root@b1:~# cat /proc/mtd dev: size erasesize name mtd0: 00800000 00010000 "fe000000.flash" mtd1: 02000000 00004000 "e0600000.flash" p.s. We can't use priv->dev->bus_id as in physmap_of, because fsl_elbc_nand pretends to be a localbus controller, so its bus_id is "address.localbus", which is incorrect and thus will also not work for multiple chips.

* [MTD] [NAND] FSL UPM NAND driverAnton Vorontsov2008-04-22
| | | | | | | | | | | This is very simple driver, NAND is connected through localbus, and User-Programmable Machine is doing various adjustments to speak NAND. No special efforts needed to do read and write cycles, though to control ALE and CLE phases, we ask UPM to generate exact pre-programmed signals on the localbus lines.

* [MTD] [NAND] support for pxa3xxeric miao2008-04-22
| | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* [MTD] [NAND] fix possible Ooops in rfc_from4Sebastian Siewior2008-04-22
| | | | | | | | | | | | | | | | | I found this while I was looking how the rs_lib is working. The rs_decoder is initialized _after_ the nand core code read the BBT table and _after_ the partition table has been added. The driver has a private BBT description which is in located in flash data so we Ooops if there is a bit flip _or_ if a bit flips while reading the partition table. This patch moves the initialization of the rs_lib before the first possible access by nand core.
