* | | [MTD] [NOR] Fixup for incorrect CFI data in Spansion S29GL064/32N flash chipsTrent Piepho2008-04-221-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a known erratum confirmed by Spansion. I have an errata document, but I can't find a link to it anywhere on their site to include here. Some of the S29GL064N chips report 64 sectors when they should report 128, and some of S29GL032N chips report 127 sectors when they should report 63. Note that when the chip dies are fixed by Spansion, they will still have the same id. The fix is done in such a way that it won't affect corrected chips. The fixups use the extended id made available by a previous patch. Without that, virtually all newer AMD/Spansion chips will have the same ID (0x227e) and it's not possible to apply the fixup to the correct chips.

* | | [MTD] [NOR] Read extended device ID from AMD/Spansion CFI flash chipsTrent Piepho2008-04-221-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AMD/Spansion use a device id of 0x7e to indicate an extended device is present at offset 0xe and 0xf in the query data. I've verified with Spansion that all their chips (mfr == 0x01) with an id of 0x7e use it to indicate an extended id is present. What's more, there are no chips with a NON-extended id that is the same as a different chip's extended id. In other words, when the extended ID is present, one can replace the normal id with the extended id without losing any information. Which is what I've done.

* | | [MTD] [NAND] fsl_elbc_nand: workaround for hangs during nand writeAnton Vorontsov2008-04-221-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Moffatt2008-04-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Vorontsov2008-04-221-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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: fix broken state in CFI driver caused by FL_SHUTDOWNAlexey Korolev2008-04-041-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | THe CFI driver in 2.6.24 kernel is broken. Not so intensive read/write operations cause incomplete writes which lead to kernel panics in JFFS2. We investigated the issue - it is caused by bug in FL_SHUTDOWN parsing code. Sometimes chip returns -EIO as if it is in FL_SHUTDOWN state when it should wait in FL_PONT (error in order of conditions). The following patch fixes the bug in state parsing code of CFI. Also I've added comments to notify developers if they want to add new case in future.
