2018-03-21mtd: Stop updating erase_info->state and calling mtd_erase_callback()Boris Brezillon
MTD users are no longer checking erase_info->state to determine if the erase operation failed or succeeded. Moreover, mtd_erase_callback() is now a NOP. We can safely get rid of all mtd_erase_callback() calls and all erase_info->state assignments. While at it, get rid of the erase_info->state field, all MTD_ERASE_XXX definitions and the mtd_erase_callback() function.

2012-03-27mtd: remove R/O checking duplicationArtem Bityutskiy
Many drivers check whether the partition is R/O and return -EROFS if yes. Let's stop having duplicated checks and move them to the API functions instead. And again a bit of noise - deleted few too sparse newlines, sorry. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2012-03-27mtd: add leading underscore to all mtd functionsArtem Bityutskiy
This patch renames all MTD functions by adding a "_" prefix: mtd->erase -> mtd->_erase mtd->read_oob -> mtd->_read_oob ... The reason is that we are re-working the MTD API and from now on it is an error to use MTD function pointers directly - we have a corresponding API call for every pointer. By adding a leading "_" we achieve the following: 1. Make sure we convert every direct pointer users 2. A leading "_" suggests that this interface is internal and it becomes less likely that people will use them directly 3. Make sure all the out-of-tree modules stop compiling and the owners spot the big API change and amend them.

2008-06-04MTD/JFFS2: remove CVS keywordsAdrian Bunk
Once upon a time, the MTD repository was using CVS. This patch therefore removes all usages of the no longer updated CVS keywords from the MTD code. This also includes code that printed them to the user. Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

2006-06-14[MTD] Restore MTD_ROM and MTD_RAM typesDavid Woodhouse
Let's not attempt the abolition of mtd->type until/unless it's properly thought through. And certainly, let's not do it by halves. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2006-05-30[MTD] replace MTD_RAM with MTD_GENERIC_TYPEJoern Engel
Ram devices get the extra capability of MTD_NO_ERASE - not requiring an explicit erase before writing to it. Currently only mtdblock uses this capability. Rest of the patch is a simple text replacement. Signed-off-by: Joern Engel <joern@wh.fh-wedel.de>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
