* mtd: Introduce mtd-peb APISascha Hauer2016-04-061-0/+9
| | | | | | | | | | | | | | Code which properly wants to handle Nand flash has to work in a block based way since blocks are the entities that are erased or may become bad. The regular mtd API works based on offsets in the device which introduces unhandy 64bit arithmetics and the requirement to align buffers to blocks. This introduces the mtd peb API (PEB for physical Erase Block) which allows the users to work in a block oriented way. The API is heavily inspired by the UBI IO layer and in fact can replace parts thereof later. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mtd: Add mtd concat supportSascha Hauer2015-06-231-0/+10
| | | | | | | | The mtd concat layer supports concatenating several MTD devices into a single one. This is nearly as-is from the corresponding Kernel code. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mtd: spi-nor: add SPI-NOR frameworkSteffen Trumtrar2015-05-291-0/+1
| | | | | | | | Import the SPI-NOR framework from linux kernel v3.19. Signed-off-by: Enrico Jorns <ejo@pengutronix.de> Signed-off-by: Steffen Trumtrar <s.trumtrar@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* nor flash: integrate into mtdSascha Hauer2013-02-141-0/+1
| | | | | | | | CFI Flash is currently handled outside the mtd layer which makes it a special case. Integrate it into mtd so that we get rid of this special status. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Cleanup Kconfig filesAlexander Shiyan2012-12-081-1/+1
| | | | | | | | | This patch provides a global cleanup barebox Kconfig files. This includes replacing spaces to tabs, formatting in accordance format, removing extraneous lines and spaces. No functional changes. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mtd Kconfig: only select NAND_READ_OOB when NAND is enabledSascha Hauer2012-01-021-2/+2
| | | | | | | | To get rid of: (MTD_OOB_DEVICE && MTD_RAW_DEVICE) selects NAND_READ_OOB which has unmet direct dependencies (MTD && NAND) Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* drivers/mtd: add docg3 chipRobert Jarzmik2012-01-021-0/+1
| | | | | | | | Add the MSystem disk-on-chip G3 support, taken from the linux kernel with few amendments to bring it into barebox. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* drivers/mtd: add the mtdraw device (data+oob)Robert Jarzmik2011-12-221-0/+6
| | | | | | | | | | | | Add a device to read and write to MTD data and oob (/dev/mtdraw<N>). The device is constrained in a separate source file, so that further improvement of commands (such as nandwrite) could make it useless, and easy to remove.

* drivers/mtd: split mtd mtdoob devicesRobert Jarzmik2011-12-221-1/+2
| | | | | | | | Split /dev/mtd and /dev/mtdoob devices. Remove from mtd structure the mtdoob character device. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* drivers/mtd: transfer NAND notions to MTD coreRobert Jarzmik2011-12-221-0/+10
| | | | | | | | | | | | | Change NAND_WRITE into MTD_WRITE. Change "page_shift" references in the core, which are purely NAND, into mtd->writesize which is MTD generic. Rename all "info" (struct mtd_info) into "mtd". Also provide a parameter to add_mtd_device() so that legacy nand devices still appear as nand<N>.
