2013-08-30mtd: mtdswap: replace strict_strtoul() with kstrtoul()Jingoo Han
The usage of strict_strtoul() is not preferred, because strict_strtoul() is obsolete. Thus, kstrtoul() should be used. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2012-01-09mtd: do not use mtd->block_markbad directlyArtem Bityutskiy
Instead, use the new 'mtd_can_have_bb()', or just rely on 'mtd_block_markbad()' return code, which will be -EOPNOTSUPP if bad blocks are not supported. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2012-01-09mtd: introduce mtd_can_have_bb helperArtem Bityutskiy
This patch introduces new 'mtd_can_have_bb()' helper function which checks whether the flash can have bad eraseblocks. Then it changes all the direct 'mtd->block_isbad' use cases with 'mtd_can_have_bb()'.

2012-01-09mtd: do not use mtd->sync directlyArtem Bityutskiy
This patch teaches 'mtd_sync()' to do nothing when the MTD driver does not have the '->sync()' method, which allows us to remove all direct 'mtd->sync' accesses. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

2012-01-09mtd: introduce mtd_erase interfaceArtem Bityutskiy
This patch is part of a patch-set which changes the MTD interface from 'mtd->func()' form to 'mtd_func()' form. We need this because we want to add common code to to all drivers in the mtd core level, which is impossible with the current interface when MTD clients call driver functions like 'read()' or 'write()' directly. At this point we just introduce a new inline wrapper function, but later some of them are expected to gain more code. E.g., the input parameters check should be moved to the wrappers rather than be duplicated at many drivers. This particular patch introduced the 'mtd_erase()' interface. The following patches add all the other interfaces one by one. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

2011-09-11mtd: rename MTD_OOB_* to MTD_OPS_*Brian Norris
These modes are not necessarily for OOB only. Particularly, MTD_OOB_RAW affected operations on in-band page data as well. To clarify these options and to emphasize that their effect is applied per-operation, we change the primary prefix to MTD_OPS_.

2011-03-25mtdswap: kill strict error handling optionYang Ruirui
As Artem Bityutskiy suggested: this option is controversial, as we do not really have any prove it is useful. And it is too much to have it as a config parameter. So, better kill it and let the real mtdswap users decide whether it is needed or not. Signed-off-by: Yang Ruirui<ruirui.r.yang@tieto.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
