================
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.

  Comments:

   * This line of SoCs is based on Marvell Sheeva or ARM Cortex CPUs
     with Synopsys DesignWare (IRQ, GPIO, Timers, ...) and PXA IP (SDHCI, USB, ETH, ...).

   * The Berlin family was acquired by Synaptics from Marvell in 2017.

CPU Cores
---------

The XScale cores were designed by Intel, and shipped by Marvell in the older
PXA processors. Feroceon is a Marvell designed core that developed in-house,
and that evolved into Sheeva. The XScale and Feroceon cores were phased out
over time and replaced with Sheeva cores in later products, which subsequently
got replaced with licensed ARM Cortex-A cores.

  XScale 1
	CPUID 0x69052xxx

  Sheeva PJ4B-MP / PJ4C
	CPUID 0x562f584x
	ARMv7, idivt/idiva, LPAE, optional iWMMXt v2 and/or NEON

Long-term plans
---------------

 * Unify the mach-dove/, mach-mv78xx0/, mach-orion5x/ 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.
