Subject: [PATCH v3 0/5] ARM: sunxi: Add basic support for Allwinner A80 SoC
Date: Wed, 8 Oct 2014 21:02:51 +0800 [thread overview]
Message-ID: <1412773376-25212-1-git-send-email-wens@csie.org> (raw)
Hi everyone,
This is v3 of the initial Allwinner A80 support series.
This patch series adds very basic support for Allwinner's A80 SoC,
a big.LITTLE architecture with 4 Cortex-A7s and 4 Cortex-A15s.
Development is done on the A80 Optimus Board, the defacto development
board for the A80, with the accompanying SDK as a reference.
So far I've been unable to get the board to boot from MMC, or
using Android fastboot. I'm using Allwinner's FEL mode to load
the bootloader and kernel+dtb image over USB. Notes on my attempts
can be found here: http://linux-sunxi.org/User:Wens#A80_Optimus
Patch 1 introduces the compatible string for the A80.
Patch 2 adds a barebone dtsi with just the cpu, memory and uart nodes.
Patch 3 adds a barebone dts for the A80 Optimus Board.
Patch 4 documents all the Allwinner SoCs we currently support.
Patch 5 updates the sunxi README with a link to the A80's datasheet.
Changes since v2:
- Dropped (unused) cpu topology map from dtsi
- Added comment on ranges usage in dtsi
- Corrected typo in bindings document
- Dropped "A80" from Kconfig sun9i machine label and DT machine
description
- Dropped 2 patches already queued:
ARM: sunxi: Add debug uart used by sun9i (Allwinner A80)
devicetree: bindings: Add vendor prefix for Merrii Technology Co.,
Ltd.
Changes since v1:
- Use skeleton64.dtsi as basis to support maximum of 8GB DRAM
- Dropped dependency on ARCH_SUNXI for DEBUG_SUN9I_UART0
- Added empty lines separating cores in the DT cpu-map node
- Added patch 7 to update sunxi README
Cheers
ChenYu
