| * | mtd: nand: omap: fix race condition in omap_wait()Ivan Djelic2012-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a context switch occurs in function omap_wait() just before the while loop is entered, then upon return from context switch the timeout may already have elapsed: in that case, status is never read from NAND device, and omap_wait() returns an error. This failure has been experimentally observed during stress tests. This patch ensures a NAND status read is always performed before returning, as in the generic nand_wait() function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some not-supported nand chips may pass the current parsing code, and get the wrong page size and oob size. Sometimes, it's hard to notice that you get the wrong values, because there is no warning or error. So it's useful to print out the page size and oob size in the end of the parsing function. We can check these values with the datasheet of the nand chip as soon as possible.

The last change to the series was before the weekend the removal of an SPI patch which Grant - even though previously acked by himself - appeared to raise objections. So I removed it until the situation is clarified. Other than that all the patches have the acks from their respective maintainers, all MIPS and x86 defconfigs are building fine and I'm not aware of any problems introduced by this series. Among the key features for this patch series is a sizable patchset for Lantiq which among other things introduces support for Lantiq's flagship product, the FALCON SOC. It also means that the opensource developers behind this patchset have overtaken Lantiq's competing inhouse development team that was working behind closed doors. Less noteworthy the ath79 patchset which adds support for a few more chip variants, cleanups and fixes. Finally the usual dose of tweaking of generic code."

Previous functionality is preserved when passing UBI_ALL for both values. The locations where ubi_wl_flush were called are appropriately changed: ubi_leb_erase only flushes for the erased LEB, and ubi_create_volume forces only flushing for its volume id. External code can call this new feature via the new function ubi_flush() added to kapi.c, which simply passes through to ubi_wl_flush(). This was tested by disabling the call to do_work in ubi thread, which results in the work queue remaining unless explicitly called to remove. UBIFS was changed to call ubifs_leb_change 50 times for four different LEBs. Then the new function was called to clear the queue: passing wrong volume ids / lnum, correct ones, and finally UBI_ALL for both to ensure it was finally all cleard. The work queue was dumped each time and the selective removal of the particular LEB numbers was observed. Extra checks were enabled and ubifs's integck was also run. Finally, the drive was repeatedly filled and emptied to ensure that the queue was cleared normally. Artem: amended the patch.

In this patch, the volume id and LEB number are added to ubi_work data structure, and both are also passed as a parameter to schedule erase to set it appropriately. Whenever ubi_wl_put_peb is called, the lnum is also passed to be forwarded to schedule erase. Later, a new ubi_sync_lnum will be added to execute immediately all work related to that lnum. This was tested by outputting the vol_id and lnum during the schedule of erasure. The ubi thread was disabled and two ubifs drives on separate partitions repeated changed a small number of LEBs. The ubi module was readded, and all the erased LEBs, corresponding to the volumes, were added to the schedule erase queue.

| * | | | | UBI: add volume id struct ubi_ainf_pebJoel Reardon2012-05-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the volume id to struct ubi_ainf_peb when scanning the LEBs at startup. PEBs now added to the erase queue will know their original LEB number and volume id, if available, and will be -1 otherwise (for instance, if the VID header is unreadable). This was tested by creating an ubi device with 3 volumes and disabiling the ubi_thread's do_work functionality. The different ubi volumes were formatted to ubifs and had files created and erased. The ubi modules was reloaded and the list of LEB's added to the erased list was outputted, confirming the volume ids and LEB numbers were appropriate.

| * | | | | UBI: add in hex the value for UBI_INTERNAL_VOL_START to commentJoel Reardon2012-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Explicitly provide the first internal volume ID value in the comment for UBI_INTERNAL_VOL_START. This allows developers who, when adding features related to volume ids and observe unexpected very large volume ids, to grep for the observed value in the source code and find out immediately that it is expected behaviour.

| * | | | | UBI: rename scan.c to attach.cArtem Bityutskiy2012-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Finally, rename the scan.c file. Now adding fastmap support won't look that hacky anymore. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
| * | | | | UBI: remove scan.hArtem Bityutskiy2012-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This file is small and it does not make sense to have it separate from where everything else lives, so merge it with ubi.h. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
| * | | | | UBI: rename UBI_SCAN_UNKNOWN_ECArtem Bityutskiy2012-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rename the constant to UBI_UNKNOWN, for the same reason that we are going to add nother attaching method and re-use the same data structures, so the "SCAN" in the name becomes incorrect. I've also removed the "_EC" part because Joel is going to use this constant for other fields in the attaching info data structures. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have a couple of initialization funcntionsn left which have "_scan" suffic - rename them: ubi_eba_init_scan() -> ubi_eba_init() ubi_wl_init_scan() -> ubi_wl_init() Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
| * | | | | UBI: amend comments after all the renamingsArtem Bityutskiy2012-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch amends commentaries in scan.[ch] to match the new logic. Reminder - we did the restructuring to prepare the code for adding the fastmap. This patch also renames a couple of functions - it was too difficult to separate out that change and I decided that it is not too bad to have it in the same patch with commentaries changes.

Also re-name it to 'early_erase_peb()' because we tend to use "ubi_" prefix only for non-static fuction and also because the new name is better.
