* | [MTD] [OneNAND] Allow for controller errors when readingAdrian Hunter2008-04-221-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | A power loss while writing can result in a page becoming unreadable. When the device is mounted again, reading that page gives controller errors. Upper level software like JFFS2 treat -EIO as fatal, refusing to mount at all. That means it is necessary to treat the error as an ECC error to allow recovery. Note that typically in this case, the eraseblock can still be erased and rewritten i.e. it has not become a bad block.

* | [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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
