Properly name the include files so that they are loaded from the <mach/*> directory and not the local directory. 2. Remove including the ts72xx.h header. This header is not generic to the ep93xx platform. It should only be included by the ts72xx specific files that require it. The only two users in the tree are arch/arm/mach-ep93xx/ts72xx.c and drivers/mtd/nand/ts7250.c. arch/arm/mach-ep93xx/include/mach/ts72xx.h 1. <linux/io.h> should already be included by any user of this header. Doing the include here hides it from being needed by the calling source file. arch/arm/mach-ep93xx/core.c 1. Remove unnecessary headers. They were probably included originally due to cut-and-paste from other files. 2. <linux/io.h> should be included not <mach/gpio.h> arch/arm/mach-ep93xx/adsphere.c arch/arm/mach-ep93xx/edb93xx.c arch/arm/mach-ep93xx/gesbc9312.c arch/arm/mach-ep93xx/micro9.c arch/arm/mach-ep93xx/ts72xx.c 1.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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>

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 '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.

| * | mtd: physmap_of: Add multiple regions and concatenation supportStefan Roese2009-06-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Stefan Roese <sr@denx.de> Reviewed-by: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
