2017-11-13mtd: remove the get_unmapped_area methodNicolas Pitre1-17/+0

2017-11-13mtd: chips/map_rom.c: implement point and unpoint methodsNicolas Pitre1-0/+25
This will allow for the removal of the get_unmapped_area method later.

2015-01-09mtd: map_rom: Support UBI on ROMAaron Sierra1-1/+12
UBI needs to know the physical erase block size, even on read-only devices, since it defines the on-device layout. Use a device-tree provided value to support previously written UBI on read-only NOR. UBI also needs a non-zero writebufsize, so we set it to one. Note: This was implemented because hardware write-protected CFI NOR cannot be probed for the physical erase block size.

2012-03-27mtd: remove R/O checking duplicationArtem Bityutskiy1-2/+1
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 Bityutskiy1-5/+5
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.

2009-03-24NOMMU: Present backing device capabilities for MTD chardevsDavid Howells1-0/+17
Present backing device capabilities for MTD character device files to allow NOMMU mmap to do direct mapping where possible. Signed-off-by: David Howells <dhowells@redhat.com> Tested-by: Bernd Schmidt <bernd.schmidt@analog.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

Which means if inftl or similar are loaded with it (which is a dumb thing to do admittedly) it may oops. Closes #8108 [dwmw2: change error to -EROFS to match write-protected flash] Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2008-06-04MTD/JFFS2: remove CVS keywordsAdrian Bunk1-1/+0
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 Woodhouse1-1/+1
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_ROM with MTD_GENERIC_TYPEJoern Engel1-4/+2
No mtd user should ever check for the device type. Instead, device features should be checked by the flags - if at all. As a first step towards type removal, change MTD_ROM into MTD_GENERIC_TYPE. Signed-off-by: Joern Engel <joern@wh.fh-wedel.de>
2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+94
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!
