mtd: spi-nor: Move m25p80 code in spi-nor.c

2019-08-12T07:54:12Z

The m25p80 driver is actually a generic wrapper around the spi-mem layer. Not only the driver name is misleading, but we'd expect such a common logic to be directly available in the core. Another reason for moving this code is that SPI NOR controller drivers should progressively be replaced by SPI controller drivers implementing the spi_mem_ops interface, and when the conversion is done, we should have a single spi-nor driver directly interfacing with the spi-mem layer. While moving the code we also fix a longstanding issue when non-DMA-able buffers are passed by the MTD layer.

docs: kbuild: convert docs to ReST and rename to *.rst

2019-06-14T20:21:21Z

The kbuild documentation clearly shows that the documents there are written at different times: some use markdown, some use their own peculiar logic to split sections. Convert everything to ReST without affecting too much the author's style and avoiding adding uneeded markups. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. 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. Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Jonathan Corbet

mtd: docg3: don't set conflicting BCH_CONST_PARAMS option

2018-11-05T08:20:37Z

I noticed during the creation of another bugfix that the BCH_CONST_PARAMS option that is set by DOCG3 breaks setting variable parameters for any other users of the BCH library code. The only other user we have today is the MTD_NAND software BCH implementation (most flash controllers use hardware BCH these days and are not affected). I considered removing BCH_CONST_PARAMS entirely because of the inherent conflict, but according to the description in lib/bch.c there is a significant performance benefit in keeping it. To avoid the immediate problem of the conflict between MTD_NAND_BCH and DOCG3, this only sets the constant parameters if MTD_NAND_BCH is disabled, which should fix the problem for all cases that are affected. This should also work for all stable kernels. Note that there is only one machine that actually seems to use the DOCG3 driver (arch/arm/mach-pxa/mioa701.c), so most users should have the driver disabled, but it almost certainly shows up if we wanted to test random kernels on machines that use software BCH in MTD.

mtd: spi-nor: Use the spi_mem_xx() API

2018-05-11T02:33:51Z

The spi_mem_xxx() API has been introduced to replace the spi_flash_read() one. Make use of it so we can get rid of spi_flash_read(). Note that using spi_mem_xx() also simplifies the code because this API takes care of using the regular spi_sync() interface when the optimized ->mem_ops interface is not implemented by the controller.
