mtd: Move onenand code base to drivers/mtd/nand/onenand

2018-03-15T14:40:37+00:00

Move onenand code base to the drivers/mtd/nand directory in the hope that someday someone will patch it to use the generic NAND helpers. If it never happens, at least we'll have all NAND related support in a single directory and not spread over the drivers/mtd/ directory. Signed-off-by: Boris Brezillon

kconfig: kill off GENERIC_IO option

2017-11-13T20:39:15+00:00

The GENERIC_IO option is set for every architecture except tile and score as those define NO_IOMEM. The option only controls visibility of CONFIG_MTD which doesn't appear to be necessary for any reason, so let's just remove GENERIC_IO.

mtd: extract TRX parser out of bcm47xxpart into a separated module

2017-06-22T20:13:10+00:00

This makes TRX parsing code reusable with other platforms and parsers. Please note this patch doesn't really change anything in the existing code, just moves it. There is still some place for improvement (e.g. working on non-hacky method of checking rootfs format) but it's not really a subject of this change.

mtd: bcm63xxpart: Remove dependency on mach-bcm63xx

2016-02-12T18:27:48+00:00

Read nvram directly from flash instead of using the in-memory copy that mach-bcm63xx has, to remove the dependency on mach-bcm63xx and allow the parser to work on bmips too. Rename remaining BCM63XX defines to BCM963XX as these are properties of the flash layout on the board. BCM963XX_DEFAULT_PSI_SIZE changes from SZ_64K to 64 because it will be multiplied by SZ_1K later on. Signed-off-by: Simon Arlott Signed-off-by: Brian Norris

mtd: enable AFS selection for ARM64

2015-11-11T01:56:05+00:00

ARM use their special partitions also on the ARM64 architecture reference designs, so enable this for ARM64. Cc: Ryan Harkin Cc: Liviu Dudau Signed-off-by: Linus Walleij Signed-off-by: Brian Norris

mtd: part: Create the master device node when partitioned

2015-04-06T00:44:01+00:00

For many use cases, it helps to have a device node for the entire MTD device as well as device nodes for the individual partitions. For example, this allows querying the entire device's properties. A common idiom is to create an additional partition which spans over the whole device. This patch makes a config option, CONFIG_MTD_PARTITIONED_MASTER, which makes the master partition present even when the device is partitioned. This isn't turned on by default since it presents a backwards-incompatible device numbering. The patch also makes the parent of a partition device be the master, if the config flag is set, now that the master is a full device. Signed-off-by: Dan Ehrenberg Signed-off-by: Brian Norris

mtd: update help of CONFIG_MTD_OF_PARTS

2014-11-05T09:17:56+00:00

The help text of CONFIG_MTD_OF_PARTS refers to additional documentation in booting-without-of.txt but this documentation was moved to another file in commit efcc2da3fd148c9acb7d7cf1d9800e0649f950fc (Stefan Roese: Factor MTD physmap bindings out of booting-without-of). This updates the help text to point to the right place. Signed-off-by: Michal Sojka [Brian: fixed doc reference] Signed-off-by: Brian Norris

mtd: spi-nor: add the framework for SPI NOR

2014-04-14T18:22:58+00:00

This patch cloned most of the m25p80.c. In theory, it adds a new spi-nor layer. Before this patch, the layer is like: MTD ------------------------ m25p80 ------------------------ spi bus driver ------------------------ SPI NOR chip After this patch, the layer is like: MTD ------------------------ spi-nor ------------------------ m25p80 ------------------------ spi bus driver ------------------------ SPI NOR chip With the spi-nor controller driver(Freescale Quadspi), it looks like: MTD ------------------------ spi-nor ------------------------ fsl-quadspi ------------------------ SPI NOR chip New APIs: spi_nor_scan: used to scan a spi-nor flash.

mtd: bcm47xxpart: allow enabling on ARCH_BCM_5301X

2014-03-11T05:42:29+00:00

Home routers based on SoCs like BCM53010 (AKA BCM4708) use flashes which can be nicely partitioned with bcm47xxpart. Header bcm47xx_nvram.h is not available on bcm53xx, so don't include it. Signed-off-by: Rafał Miłecki Signed-off-by: Brian Norris

mtd: Hide CONFIG_MTD_BLKDEVS from the menu

2014-01-07T18:07:36+00:00

Make this option a hidden one and get a cleaner configuration. This option just selects a common infrastructure for MTD-based devices to expose a block interface. There is no point in allowing a separate enable/disable. Signed-off-by: Ezequiel Garcia [Brian: keep symbol as tristate] Signed-off-by: Brian Norris
