Thomas Petazzoni 0d9ab18e33 Documentation: arm: update supported Marvell EBU processors
Now that we support Armada 39x, let's add this family of SoC to the
Marvell documentation, and a reference to a link with more details
about those processors. Unfortunately, no datasheet is publicly
available at this time.

Thomas Petazzoni feb60beacd Documentation: arm: add hardware datasheet reference for Marvell Armada XP
Some time ago, the "Function Specifications" for the Marvell Armada XP
processor has been released. However, the "Hardware Specifications"
were not released at the same time. They have now been released
publicly, so this commit updates the Marvell documentation file with
the references to this new documentation.

Three documents are available, one for each of the three variants of
Armada XP: 78230, 78260 and 78460.

Thomas Petazzoni b6e9f52190 Documentation: arm: misc updates to Marvell EBU SoC status
Following the merging of mach-kirkwood into mach-mvebu, the removal of
mach-kirkwood, and the progress of the integration of mach-dove into
mach-mvebu, this commit makes a few updates to the Marvell README file
in the kernel documentation.

Thomas Petazzoni 35d324d625 Documentation: arm: add URLs to public datasheets for the Marvell Armada XP SoC
Marvell has very recently released a public version of the "Functional
specifications" and "Hardware specifications" datasheets for the
Marvell Armada XP SoC. This allows contributors and developers not
under NDA with Marvell to get more details about this SoC than what
the current kernel code shows, and hopefully allows to improve the
support for this SoC in the mainline kernel, as well as in other
projects.

Thomas Petazzoni bc81526f37 Documentation: arm: update Marvell documentation about Armada 375/38x
This commit updates the documentation that describes the various
families of SOCs produced by Marvell, together with the corresponding
available technical documents. It adds Armada 375 and Armada 38x, and
adds a link to the product brief for the already supported Armada 370.

Kevin Hilman d7f5baeedb Documentation: arm/Marvell: clarify Armada SoCs that match 78xx0 pattern
New users of Marvell SoCs will potentially be confused by the MVEBU
SoCs that match the 78xx0 pattern and thus which defconfig and mach-*
directory to be looking at.  Add a bit of clarification to README for
this.

Thomas Petazzoni 9ee99783d7 arm: add documentation describing Marvell families of SoC
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 v3:
 * Add Arnd Bergmann Acked-by.

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.
