Subject: [U-Boot] [PATCH 0/9] tegra2: Tidy up boot path
Date: Thu, 13 Oct 2011 14:05:54 -0700 [thread overview]
Message-ID: <1318539963-3329-1-git-send-email-sjg@chromium.org> (raw)
On Tegra2 the AVP runs the normal U-Boot code to a point, then halts and
the A9 takes over. The current Tegra2 boot path is fairly complex, since it
has a separate path and code for the Cortex-A9 and the AVP. In fact, they
can largely execute the same code path.
This series cleans up this logic and removes some parallel and un-needed
code.
Simon Glass (9):
tegra2: Add arch_cpu_init() to fire up Cortex-A9
tegra2: Simplify tegra_start() boot path
arm: Move CP15 init out of cpu_init_crit()
tegra2: Enable instruction cache
tegra2: Remove unneeded boot code
tegra2: Remove unneeded config option
tegra2: Remove unused low-level Tegra2 UART code
tegra2: Remove unneeded 'dynamic ram size' message
tegra2: Don't use board pointer before it is set up
