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

      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.
