   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.

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

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

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

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