[U-Boot] [PATCH v3 0/8] 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

Changes in v3:
- Update comment and also make it match style
- Fix cpu_init_cp15() name
- Remove exporting of cpu_init_cp15() from start.S
- Add test for ARMv7 CPU and skip CP15 init if not found
- Add lowlevel_init function back in (though it does nothing)
- Remove later CP15 init in board.c since this is not needed now
- Rebase against master (due to CONFIG_SYS_CACHELINE_SIZE series)

Simon Glass (8):
  tegra2: Add arch_cpu_init() to fire up Cortex-A9
  tegra2: Simplify tegra_start() boot path
  arm: Only do CP15 init on ARMv7
  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
