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.

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: NArtem Bityutskiy <Artem.Bityutskiy@nokia.com>

Use BLOCK_NIL consistently rather than sometimes 0xffff and sometimes BLOCK_NIL. The semantic patch that finds this issue is below (http://www.emn.fr/x-info/coccinelle/). On the other hand, the changes were made by hand, in part because drivers/mtd/inftlcore.c contains dead code that causes spatch to ignore a relevant function. Specifically, the function INFTL_findwriteunit contains a do-while loop, but always takes a return that leaves the loop on the first iteration. // <smpl> @r exists@ identifier f,C; @@ f(...) { ... return C; } @s@ identifier r.C; expression E; @@ @@ identifier r.f,r.C,I; expression s.E; @@ f(...) { <...

The UBIFS WL worker may encounter read errors and there is logic which makes a decision whether we should do one of: 1. cancel the operation and move the PEB with the read errors to the 'erroneous' list; 2. switch to R/O mode. ATM, only -EIO errors trigger 1., other errors trigger 2. The idea is that if we know we encountered an I/O error, do 1. Otherwise, we do not know how to react, and do 2., just in case. E.g., if the underlying driver became crazy because of a bug, we do not want to harm any data, and switch to R/O mode. This patch does 2 things: 1. Makes sure reads from the source PEB always cause 1. This is more consistent with other reads which come from the upper layers and never cause R/O. 2. Teaches UBI to do 1. also on -EBADMSG, UBI_IO_BAD_VID_HDR, -ENOMEM, and -ETIMEOUT. But this is only when reading the target PEB. This preblems were hunted by Adrian Hunter.

Commit 81933046 ('mtd: Fix handling of mtdname in txx9ndfmc.c') introduced a potential memory leak. The 'mtdname' member of the private data structure is now allocated separately, but was not freed on certain error paths. Fix that, and make things simpler by _always_ allocating it separately so that we don't need 'if (mtdname != dev_name()) kfree(mtdname);'... which gets ugly now that we're doing it more than once, and more likely that we'll get it wrong some time.

This patch adds support to handle multiple non-identical chips in one flash device tree node. It also adds concat support to physmap_of. This makes it possible to support e.g. the Intel P30 48F4400 chips which internally consists of 2 non-identical NOR chips on one die. Additionally partitions now can span over multiple chips. To describe such a chip's, multiple "reg" tuples are now supported in one flash device tree node. Here an dts example: flash@f0000000,0 { #address-cells = <1>; #size-cells = <1>; compatible = "cfi-flash"; reg = <0 0x00000000 0x02000000 0 0x02000000 0x02000000>; bank-width = <2>; partition@0 { label = "test-part1"; reg = <0 0x04000000>; }; }; Signed-off-by: NStefan Roese <sr@denx.de> Reviewed-by: NGrant Likely <grant.likely@secretlab.ca> Signed-off-by: NDavid Woodhouse <David.Woodhouse@intel.com>

Due to a processor anomaly (05000263 to be exact), most Blackfin parts cannot keep the embedded filesystem image directly after the kernel in RAM.
