Merge tag 'docs' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM soc documentation updates from Olof Johansson:
 "Documentation update for Marvell SoCs, the secret decoder ring to all
  their crazy product names and numbers."

* tag 'docs' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
  arm: add documentation describing Marvell families of SoC
parents e7b5ec99 c1faefbb
ARM Marvell SoCs
================
This document lists all the ARM Marvell SoCs that are currently
supported in mainline by the Linux kernel. As the Marvell families of
SoCs are large and complex, it is hard to understand where the support
for a particular SoC is available in the Linux kernel. This document
tries to help in understanding where those SoCs are supported, and to
match them with their corresponding public datasheet, when available.

Comments:
* This line of SoCs originates from the XScale family developed by
Intel and acquired by Marvell in ~2006. The PXA21x, PXA25x,
PXA26x, PXA27x, PXA3xx and PXA93x were developed by Intel, while
the later PXA95x were developed by Marvell.
* Due to their XScale origin, these SoCs have virtually nothing in
common with the other (Kirkwood, Dove, etc.) families of Marvell
SoCs, except with the MMP/MMP2 family of SoCs.

Long-term plans
---------------
* Unify the mach-dove/, mach-mv78xx0/, mach-orion5x/ and
mach-kirkwood/ into the mach-mvebu/ to support all SoCs from the
Marvell EBU (Engineering Business Unit) in a single mach-<foo>
directory. The plat-orion/ would therefore disappear.
* Unify the mach-mmp/ and mach-pxa/ into the same mach-pxa
directory. The plat-pxa/ would therefore disappear.
