Merge git://git.infradead.org/mtd-2.6
* git://git.infradead.org/mtd-2.6: (226 commits) mtd: tests: annotate as DANGEROUS in Kconfig mtd: tests: don't use mtd0 as a default mtd: clean up usage of MTD_DOCPROBE_ADDRESS jffs2: add compr=lzo and compr=zlib options jffs2: implement mount option parsing and compression overriding mtd: nand: initialize ops.mode mtd: provide an alias for the redboot module name mtd: m25p80: don't probe device which has status of 'disabled' mtd: nand_h1900 never worked mtd: Add DiskOnChip G3 support mtd: m25p80: add EON flash EN25Q32B into spi flash id table mtd: mark block device queue as non-rotational mtd: r852: make r852_pm_ops static mtd: m25p80: add support for at25df321a spi data flash mtd: mxc_nand: preset_v1_v2: unlock all NAND flash blocks mtd: nand: switch `check_pattern()' to standard `memcmp()' mtd: nand: invalidate cache on unaligned reads mtd: nand: do not scan bad blocks with NAND_BBT_NO_OOB set mtd: nand: wait to set BBT version mtd: nand: scrub BBT on ECC errors ... Fix up trivial conflicts: - arch/arm/mach-at91/board-usb-a9260.c Merged into board-usb-a926x.c - drivers/mtd/maps/lantiq-flash.c add_mtd_partitions -> mtd_device_register vs changed to use mtd_device_parse_register.

The simplest way to activate the FLASH based bad block table support

chips is this done by default.

This activates the default FLASH based bad block table functionality

* 'parse_mtd_partitions()' for more information
|
||||
* @parser_data: MTD partition parser-specific data
|
||||
* @parts: fallback partition information to register, if parsing fails;
|
||||
* only valid if %nr_parts > %0
|
||||
* @nr_parts: the number of partitions in parts, if zero then the full
|
||||
* MTD device is registered if no partition info is found
|
||||
*
|
||||
* Register an MTD device with the system and optionally, a number of
|
||||
* partitions. If nr_parts is 0 then the whole device is registered, otherwise
|
||||
* only the partitions are registered. To register both the full device *and*
|
||||
* the partitions, call mtd_device_register() twice, once with nr_parts == 0
|
||||
* and once equal to the number of partitions.
|
||||
* This function aggregates MTD partitions parsing (done by
|
||||
* 'parse_mtd_partitions()') and MTD device and partitions registering. It
|
||||
* basically follows the most common pattern found in many MTD drivers:
|
||||
*
|
||||
* * It first tries to probe partitions on MTD device @mtd using parsers
|
||||
* specified in @types (if @types is %NULL, then the default list of parsers
|
||||
* is used, see 'parse_mtd_partitions()' for more information). If none are
|
||||
* found this functions tries to fallback to information specified in
|
||||
* @parts/@nr_parts.
|
||||
* * If any partitioning info was found, this function registers the found
|
||||
* partitions.
|
||||
* * If no partitions were found this function just registers the MTD device
|
||||
* @mtd and exits.
|
||||
*
|
||||
* Returns zero in case of success and a negative error code in case of failure.
