2011-04-05UBI: do not select KALLSYMS_ALLArtem Bityutskiy
All UBI needs is to make sure we stacktraces when UBI debugging is enabled. It is enough to select KALLSYMS for this, KALLSYMS_ALL is not necessary. And the current Kconfig line we have: select KALLSYMS_ALL if KALLSYMS && DEBUG_KERNEL is just too complex to be sane and right. But this "if" part there is needed to prevent "unmet direct dependency" warnings, because KALLSYMS_ALL depends on KALLSYMS and DEBUG_KERNEL, so we cannot just select KALLSYMS_ALL. Anyway, this feels messy, and we do not seem to really need KALLSYMS_ALL, so select KALLSYMS instead.

2011-04-05UBI: do not compare array with NULLArtem Bityutskiy

2011-04-05UBI: check if we are in RO mode in the erase routineArtem Bityutskiy
'do_sync_erase()' has to check whether we are in R/O mode before erasing the PEB. This patch adds the check and while on it, adds an assertion which validates the 'pnum' argument, as well as removes a check which is always true because it has already been done few lines before.

NOTE! This merge commit was created to fix compilation error. The block tree was merged upstream and removed the 'elv_queue_empty()' function which the new 'mtdswap' driver is using. So a simple merge of the mtd tree with upstream does not compile. And the mtd tree has already be published, so re-basing it is not an option. To fix this unfortunate situation, I had to merge upstream into the mtd-2.6.git tree without committing, put the fixup patch on top of this, and then commit this. The result is that we do not have commits which do not compile. In other words, this merge commit "merges" 3 things: the MTD tree, the upstream tree, and the fixup patch.

2011-03-16UBI: make tests modes dynamicArtem Bityutskiy
Similarly to the debugging checks and message, make the test modes be dynamically selected via the "debug_tsts" module parameter or via the "/sys/module/ubi/parameters/debug_tsts" sysfs file. This is consistent with UBIFS as well. And now, since all the Kconfig knobs became dynamic, we can remove the Kconfig.debug file completely.

2011-03-16UBI: make self-checks dynamicArtem Bityutskiy
This patch adds a possibility to dynamically switch UBI self-checks on and off, instead of toggling them compile-time from the configuration menu. This is much more flexible, and consistent with UBIFS, and this also simplifies UBI Kconfig menu and the code. This patch introduces two levels of self-checks - general, which includes all self-checks which are relatively fast, and I/O, which includes write-verify checks and erase-verify checks, which are relatively slow and involve flash I/O.

2011-03-16UBI: kill debugging bufferArtem Bityutskiy
This patch kills the 'ubi->dbg_peb_buf' debugging buffer and the associated mutex, because all users of this buffer are now gone. We are killing this buffer because we are going to switch to dynamic debugging control, just like in UBIFS, which means that CONFIG_MTD_UBI_DEBUG_PARANOID will be removed. In this case we'd end up always allocating 'ubi->dbg_peb_buf', which is rather large (128KiB or more), and this would be wasteful. Thus, we are just killing it.

The intend is to get rid of the pre-allocated 'ubi->dbg_peb_buf' buffer completely. And the need for this arises because we want to change to dynamic debugging control instead of compile-time control, i.e., we are going to kill the CONFIG_MTD_UBI_DEBUG_PARANOID Kconfig option, which would mean that 'ubi->dbg_peb_buf' is always allocated, which would be wasteful.

2011-03-11mtd: nand: add software BCH ECC supportIvan Djelic
This patch adds software BCH ECC support to mtd, in order to handle recent NAND device ecc requirements (4 bits or more). It does so by adding a new ecc mode (NAND_ECC_SOFT_BCH) for use by board drivers, and a new Kconfig option to enable BCH support. It relies on the generic BCH library introduced in a previous patch. When a board driver uses mode NAND_ECC_SOFT_BCH, it should also set fields chip->ecc.size and chip->ecc.bytes to select BCH ecc data size and required error correction capability. See nand_bch_init() documentation for details. It has been tested on the following platforms using mtd-utils, UBI and UBIFS: x86 (with nandsim), arm926ejs.

The DaVinci NAND driver was including the mach-types.h header file. This prevented the DaVinci NAND driver from getting used in a DSP only device. The linux port on c6x devices can make use of the same driver and does not define a corresponding header file. This header file was required in the driver because earlier there was code dependent on a machine_* check.
