2014-09-17Documentation: arm: add hardware datasheet reference for Marvell Armada XPThomas Petazzoni
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.

2014-07-25Documentation: arm: misc updates to Marvell EBU SoC statusThomas Petazzoni
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.

2014-07-25Documentation: arm: add URLs to public datasheets for the Marvell Armada XP SoCThomas Petazzoni
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.

2014-02-22Documentation: arm: update Marvell documentation about Armada 375/38xThomas Petazzoni
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.

2013-10-08Documentation: arm/Marvell: clarify Armada SoCs that match 78xx0 patternKevin Hilman
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.

2012-08-11arm: add documentation describing Marvell families of SoCThomas Petazzoni
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.
