[U-Boot] [PATCH v2 0/9] tegra2: Tidy up boot path

[Simon Glass]

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.

Changes in v2:
- Move Makefile armv4t flags from arch/arm/lib to Tegra's config.mk
- Keep Tegra's config.mk file around so we can set the armv4t flags

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
