Subject: [U-Boot] [PATCH] Add A9 CPU complex support
Date: Wed, 16 Feb 2011 13:26:03 -0700 [thread overview]
Message-ID: <1297887964-25207-1-git-send-email-twarren@nvidia.com> (raw)
This patch adds code to initialize the A9 dual CPU complex
in the Tegra2 SoC. The code is run on the AVP first to set
up the A9 and Coresight clocks, then the AVP is halted, the
A9 CPU is brought out of reset, and the code executes again
on the CPU, but down a slightly different path. Normal POST
then proceeds using the A9 CPU.
