Hello,
This is the third version of the patch series adding Armada 39x basic
support.
This set of patches add basic support for a new family of Marvell EBU
processors: the Armada 39x. They are based on Cortex-A9 (like Armada
375 and 38x) and the most important new feature is probably the
addition of 10 GbE support.
See http://www.marvell.com/embedded-processors/armada-39x/ for a basic
introduction.
Note that this web page talks about an Armada 395 and Armada 398, but
so far the technical documentation we have been given access to only
describes Armada 390 and Armada 398, so this series supports only
Armada 390 and Armada 398 so far. Support for Armada 395 might be
added in the future, once we get access to the appropriate technical
details.
Changes v2 -> v3:
- Rebased on top of v4.0-rc1
- Add support for the L2 cache
- Added Acked-by from Gregory Clement on
ARM: mvebu: add __initconst specifiers on DT_MACHINE_START dt_compat tables
ARM: mvebu: fix usb@ unit address on Armada 38x to match register address
ARM: mvebu: add missing UART alias on Armada 38x
devicetree: bindings: add DT binding for the Marvell Armada 39x SoC family
- Renamed 'ARM: mvebu: add missing UART alias on Armada 38x' to 'ARM:
mvebu: add missing UART labels on Armada 38x'.
- Added a patch 'ARM: mvebu: add UART labels to Armada 375'.
- Change 'ARM: mvebu: add stdout-path to all armada-*.dts' to go
further and eliminate completely /chosen/bootargs. This removes the
non-desired 'earlyprintk' argument, and since console= was the only
remaining kernel parameter, using stdout-path makes more
sense. Requested by Rob Herring and Mark Rutland.
- Dropped the patch "ARM: mvebu: use IRQ macros to define the SDHCI
interrupt on Armada 38x" from the series, since Gregory Clement
already submitted it as part of a different series.
- Added patches 'ARM: mvebu: enable Armada 39x in mvebu_v7_defconfig'
and 'ARM: configs: enable Marvell Armada 39x in multi_v7_defconfig'
to update mvebu_v7_defconfig and multi_v7_defconfig so that they
enable Marvell Armada 39x by default. Suggested by Gregory Clement.
- Fix the unit address of the MPIC interrupt controller, in both the
newly added Armada 39x support, as well as in the existing Armada
370, 375, 38x and XP support. Suggested by Gregory Clement.
Changes v1 -> v2:
- At the SoC level, add the description of SPI controller 0 and 1,
NAND flash controller, SDHCI controller, Core Divider Clock (needed
by the NAND flash controller), the main PLL clock (needed by the
Core Divider Clock) and the XOR engines.
- At the board level, add the description of the SPI flash connected
to SPI bus 1, which contains the bootloader, and the description of
the NAND flash.
- Fix space vs. tab.
- Use __initconst when defining the dt_compat table for Armada
39x. Suggested by Stephen Boyd.
- Fix typo in commit log of "ARM: mvebu: add core support for Armada
39x", noticed by Maxime Ripard.
- Remove earlyprintk from /chosen/bootargs. Suggested by Andrew Lunn.
- Add aliases for uart[0-3]. Suggested by Andrew Lunn.
- Add /chosen/stdout-path to Armada 398 DB DT. Suggested by Andrew
Lunn.
- Move pinctrl configurations at the SoC level. Suggested by Andrew
Lunn.
- Add several preparation/cleanup patches not related to Armada 39x
directly, but whose topics were found while working on Armada 39x
support:
- Add __initconst to all dt_compat table in mach-mvebu.
- Fixup usb@ unit address on Armada 38x
- Add stdout-path to all armada-*.dts
- Use GIC and IRQ macros in SDHCI definition of Armada 38x
- Add missing UART alias on Armada 38x
Thanks!
