Mainline Linux tree for various devices, only for fun :)

Optimezed mem*io operations are defined for LE platforms, use them. The ARM and !ARCH_EBSA110 dependencies for COMPILE_TEST were added only for the _memcpy_fromio()/_memcpy_toio() functions. Drop these dependencies. Tested unaligned accesses on both sama5d2 and sam9x60 QSPI controllers using SPI NOR flashes, everything works ok. The following performance improvement can be seen when running mtd_speedtest: sama5d2_xplained (mx25l25635e) - before: mtd_speedtest: eraseblock write speed is 983 KiB/s mtd_speedtest: eraseblock read speed is 6150 KiB/s - after: mtd_speedtest: eraseblock write speed is 1055 KiB/s mtd_speedtest: eraseblock read speed is 20144 KiB/s sam9x60ek (sst26vf064b) - before: mtd_speedtest: eraseblock write speed is 4770 KiB/s mtd_speedtest: eraseblock read speed is 8062 KiB/s - after: mtd_speedtest: eraseblock write speed is 4524 KiB/s mtd_speedtest: eraseblock read speed is 21186 KiB/s Signed-off-by: Tudor Ambarus <tudor.ambarus@microchip.com> Link: https://lore.kernel.org/r/20200716043139.565734-1-tudor.ambarus@microchip.com Signed-off-by: Mark Brown <broonie@kernel.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
