2023-04-04mtd: spi-nor: Stop exporting spi_nor_restore()Tudor Ambarus
Some SPI NOR controllers that used this method were moved to drivers/spi/. We don't accept new support for the existing SPI NOR controllers drivers under drivers/mtd/spi-nor/controllers/ and we encourage their owners to move the drivers under drivers/spi/. Make spi_nor_restore() private as we're going to use it just in core.c.

2022-02-14Documentation / MTD: Rename the intel-spi driverMika Westerberg
Since the driver is renamed (and moved) update the BIOS upgrade guide accordingly from intel-spi to spi-intel. Keep the guide under MTD documentation because this is pretty much still about MTD and SPI-NOR.

Moving files around produced the following warnings: Error: Cannot open file drivers/mtd/nand/raw/nand_ecc.c Error: Cannot open file drivers/mtd/nand/raw/nand_ecc.c Fix one by just dropping the reference because it is not relevant, the other by using a better noun instead of a file name.

Currently, all diagrams below "Before this framework, the layer is like" and the text in between are rendered as one monospace text block. Instead, each individual diagram should be a monospace text block.

2019-07-15docs: mtd: move it to the driver-api bookMauro Carvalho Chehab
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. Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
