[PATCH] arm: add documentation describing Marvell families of SoC
Thomas Petazzoni

Sat Aug 4 17:16:44 EDT 2012
As stated in the introduction of the document, the families of ARM
SoCs at Marvell are very complicated, and it is difficult for
newcomers to understand the organization of this SoC family and how it
relates to the Linux kernel support for those hardware platforms.
This document is only at RFC stage for now, it requires reviews and
comments from the Marvell maintainers, the PXA maintainers and the MMP
maintainers. For correctness of course, but also to add any other
information that would be useful. For example, one of the thing that
wasn't clear how to detail in the documentation is how the SoCs relate
to each other in terms of hardware IP blocks. For example, most of the
Kirkwood/Dove/Armada 370-XP/etc. hardware IPs (I2C, SPI, USB, SATA,
etc.) are identical, while the PXA and MMP families are completely
separate.

Changes from v2:
* Mention the plat-<foo> directory that each SoC family is using.
* Take into account Eric Miao's comments on the PXA/MMP families: add
PXA21x/PXA25x/PXA26x to the list, mention which processors are
AP+CP or AP only. Clarify the comments on which SoCs were designed
by Intel, which ones were designed by Marvell after the acquisition
of the XScale family.
* Mention long-term plans regarding the support of those SoC
families.
Changes from v1:
* Added publicly available datasheet for the 88F5182 pointed by
Andrew Lunn.
* Added publicly available datasheet for the 88F5281 found with
Google searches
* Mentionned the Feroceon core name where appropriate, and Sheeva
where appropriate
* Fixed the core names for PXA930, PXA935 and PXA955 after comments
from Arnd Bergmann. Wikipedia is mistakenly suggesting that PXA93x
are Sheeva-based, and there isn't much information available on the
web about the 955.

+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.

+ * This line of SoCs originates from the XScale family developed by

+ 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.

+
+ * Unify the mach-mmp/ and mach-pxa/ into the same mach-pxa
