   5 This document lists all the ARM Marvell SoCs that are currently
   6 supported in mainline by the Linux kernel. As the Marvell families of
   7 SoCs are large and complex, it is hard to understand where the support
   8 for a particular SoC is available in the Linux kernel. This document
   9 tries to help in understanding where those SoCs are supported, and to
  10 match them with their corresponding public datasheet, when available.

 344     * This line of SoCs originates from the XScale family developed by
 345       Intel and acquired by Marvell in ~2006. The PXA21x, PXA25x,
 346       PXA26x, PXA27x, PXA3xx and PXA93x were developed by Intel, while
 347       the later PXA95x were developed by Marvell.
 348
 349     * Due to their XScale origin, these SoCs have virtually nothing in
 350       common with the other (Kirkwood, Dove, etc.) families of Marvell
 351       SoCs, except with the MMP/MMP2 family of SoCs.

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

 449 ---------
 450
 451 The XScale cores were designed by Intel, and shipped by Marvell in the older
 452 PXA processors. Feroceon is a Marvell designed core that developed in-house,
 453 and that evolved into Sheeva. The XScale and Feroceon cores were phased out
 454 over time and replaced with Sheeva cores in later products, which subsequently
 455 got replaced with licensed ARM Cortex-A cores.

 491 Long-term plans
 492 ---------------
 493
 494  * Unify the mach-dove/, mach-mv78xx0/, mach-orion5x/ into the
 495    mach-mvebu/ to support all SoCs from the Marvell EBU (Engineering
 496    Business Unit) in a single mach-<foo> directory. The plat-orion/
 497    would therefore disappear.
 498
 499  * Unify the mach-mmp/ and mach-pxa/ into the same mach-pxa
 500    directory. The plat-pxa/ would therefore disappear.
