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.

   Comments:

    * This line of SoCs originates from the XScale family developed by
      Intel and acquired by Marvell in ~2006. All the processors of
      this MMP/MMP2 family 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 PXA family of SoCs listed above.

   Linux kernel mach directory: arch/arm/mach-mmp
   Linux kernel plat directory: arch/arm/plat-pxa

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.
