docs: mtd: move it to the driver-api book

2019-07-15T12:20:28+00:00

While I was tempted to move it to admin-guide, as some docs
there are more userspace-faced, there are some very technical
discussions about memory error correction code from the Kernel
implementer's PoV. So, let's place it inside the driver-api
book.

docs: mtd: convert to ReST

2019-07-15T12:20:25+00:00

Rename the mtd documentation files to ReST, add an
index for them and adjust in order to produce a nice html
output via the Sphinx build system.

It should be noticed that Sphinx doesn't handle very well
URLs with dots in the middle. Thankfully, internally, the '.'
char is translated to %2E, so we can jus use %2E instead of
dots, and this will work fine on both text and processed files.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

Documentation: mtd: remove stale pxa3xx NAND controller documentation

2018-09-04T21:37:38+00:00

It is preferred to have the documentation about the drivers directly
embedded in the driver itself. Remove this file now that the most
important information from this file have been re-written in
marvell_nand.c.

mtd: spi-nor: add an API to restore the status of SPI flash chip

2017-12-12T23:36:00+00:00

Add this API to restore the status of SPI flash chip to the default
such as addressing mode, whenever detach the driver from device or
reboot the system.

spi-nor: Add support for Intel SPI serial flash controller

2017-01-03T17:33:36+00:00

Add support for the SPI serial flash host controller found on many Intel
CPUs including Baytrail and Braswell. The SPI serial flash controller is
used to access BIOS and other platform specific information. By default the
driver exposes a single read-only MTD device but with a module parameter
"writeable=1" the MTD device can be made read-write which makes it possible
to upgrade BIOS directly from Linux.

Documentation: mtd: improve nand_ecc.txt for readability and correctness

2015-11-18T01:05:14+00:00

This patch correct some representation errors, add a little
clarification in some places, and fix indentation problems
for pseudo code.

It also delete one more white space for one place.

Merge tag 'for-linus-20140610' of git://git.infradead.org/linux-mtd

2014-06-11T15:35:34+00:00

Pull MTD updates from Brian Norris:
 - refactor m25p80.c driver for use as a general SPI NOR framework for
   other drivers which may speak to SPI NOR flash without providing full
   SPI support (i.e., not part of drivers/spi/)
 - new Freescale QuadSPI driver (utilizing new SPI NOR framework)
 - updates for the STMicro "FSM" SPI NOR driver
 - fix sync/flush behavior on mtd_blkdevs
 - fixup subpage write support on a few NAND drivers
 - correct the MTD OOB test for odd-sized OOB areas
 - add BCH-16 support for OMAP NAND
 - fix warnings and trivial refactoring
 - utilize new ECC DT bindings in pxa3xx NAND driver
 - new LPDDR NVM driver
 - address a few assorted bugs caught by Coverity
 - add new imx6sx support for GPMI NAND
 - use a bounce buffer for NAND when non-DMA-able buffers are used
