mtd: chips: Use SPDX license headers

2023-06-09T15:27:11+00:00

Some of the files in mtd/chips do not have a SPDX license header, presumably because the text string "GPL'd" didn't parse with Thomas rulesets for magic license tagging. Fix this, the code is initially from RedHat which clearly targeted the Linux kernel and intended it to be GPLv2. In any case the original author appears to be David Woodhouse who can then confirm this.

mtd: map_rom: Support UBI on ROM

2015-01-10T07:24:27+00:00

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.

mtd: remove R/O checking duplication

2012-03-26T23:29:11+00:00

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 Signed-off-by: David Woodhouse

mtd: add leading underscore to all mtd functions

2012-03-26T23:20:01+00:00

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. Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

MTD/JFFS2: remove CVS keywords

2008-06-04T16:50:17+00:00

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 This patch therefore removes all usages of the no longer updated CVS keywords from the MTD code.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 Signed-off-by: David Woodhouse
