2009-09-23spi: prefix modalias with "spi:"Anton Vorontsov
This makes it consistent with other buses (platform, i2c, vio, ...). I'm not sure why we use the prefixes, but there must be a reason. This was easy enough to do it, and I did it.

I've discussed this at gcc-help, refer to the thread at http://gcc.gnu.org/ml/gcc-help/2009-08/msg00187.html The early clobber is added to avoid the destination registers and the source register overlapping.

2009-08-14UBI: improve NOR flash erasure quirkArtem Bityutskiy
More testing of NOR flash against power cuts showed that sometimes eraseblocks may be unwritable, and we cannot really invalidate them before erasure. But in this case the eraseblock probably contains garbage anyway, and we do not have to invalidate the headers. This assumption might be not true, but this is at least what I have observed. So if we cannot invalidate the headers, we make sure that the PEB does not contain valid VID header. If this is true, everything is fine, otherwise we panic.

2009-08-14UBI: print a warning if too many PEBs are corruptedArtem Bityutskiy
There was a bug report recently where UBI prints: UBI error: ubi_attach_mtd_dev: failed to attach by scanning, error -22 error messages and refuses to attach a PEB. It turned out to be a buggy flash driver which returned garbage to almost every UBI read. This patch makes UBI print a better message in such cases. Namely, if UBI finds 8 or more corrupted PEBs, it prints a warning and lists the corrupted PEBs. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2009-08-14UBI: amend NOR flash pre-erase quirkArtem Bityutskiy
In case of NOR flash, UBI zeroes EC and VID headers' magic, in order to detect interrupted erasures. It first zeroes out the EC magic, then VID magic. However, if a power cut happens in between, we'll end up with a corrupted EC header and a valid VID header, in which case UBI accepts the PEB, but prints a warning. This patch makes sure we first zero out the VID magic, then the EC magic, not vice versa. This is just a small amendment to prevent warning messages.

2009-08-14UBI: print a message if ECH is corrupted and VIDH is okArtem Bityutskiy

2009-07-07UBI: fix NOR flash recoveryArtem Bityutskiy
This commit fixes NOR flash recovery issues observed with Spansion S29GL512N NOR. When NOR erases, it first fills PEBs with zeroes, then sets all bytes to 0xFF. Filling with zeroes starts from the end of the PEB. And when power is cut, this results in PEBs containing correct EC and VID headers but corrupted with zeros at the end. This confuses UBI and it mistakinly accepts these PEBs and associate them with LEBs. Fis this issue by zeroing EC and VID magics before erasing PEBs, to make UBI later refuse zem.

2009-07-05UBI: remove bogus debugging checksArtem Bityutskiy
The 'paranoid_check_empty()' is bogus because, which is easilly seen on NOR flash, which has long erase cycles, and which may easilly end-up with half-erased eraseblocks. In this case the paranoid check fails. I is just wrong to assume that PEBs which do not have EC headers always contain all 0xFF. Such assumption should not be made on the I/O level, which is quite low. Thus, just kill the check. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
