Subject: [U-Boot] [RFC PATCH 0/8] Allwinner A83T PSCI SMP support
Date: Wed, 7 Jun 2017 08:47:13 +0800 [thread overview]
Message-ID: <20170607004721.24194-1-icenowy@aosc.io> (raw)
This is an experimental support for the PSCI SMP bringup of the first
cluster of Allwinner A83T SoC.
It's based on some code by Timothy Pearson for A83T (already quite old)
and Chen-Yu Tsai (which are originally for A80).
In order to ensure the Linux kernel to work properly in SMP environment,
some GIC workarounds implemented in [1] is needed.
[1] https://github.com/wens/linux/commit/c48654c1f737116e7a7660183c8c74fa91970528
Chen-Yu Tsai (2):
sunxi: Add CPUCFG register definitions for A80/A83T SoCs
sunxi: Add basic PSCI implementation for multi-cluster SoCs
Icenowy Zheng (4):
sunxi: add configuration of secure SRAM for A83T
sunxi: add SUNXI_R_CPUCFG_BASE for A83T SoC
sunxi: add multi-cluster CPU PRCM register definition
sunxi: enable PSCI for A83T SoC
tpearson at raptorengineering.com (2):
sun8i: Add TZPC setup for A83T
sun8i: Add a macro to read the silicon revision
