commit a9f8f6cab3cc5cd8535db31fd452fd07c173ffcf Author: Furquan Shaikh furquan@google.com Date: Mon Jun 9 13:20:04 2014 -0700
tegra132: Enable bootblock support in tegra132 including UART support
BUG=None BRANCH=None TEST=Compiles successfully
Original-Change-Id: Ia9420cfec5333dd5477f04cf080bdad8a37db025 Original-Signed-off-by: Furquan Shaikh furquan@google.com Original-Reviewed-on: https://chromium-review.googlesource.com/203143 Original-Tested-by: Furquan Shaikh furquan@chromium.org Original-Reviewed-by: Aaron Durbin adurbin@chromium.org Original-Commit-Queue: Aaron Durbin adurbin@chromium.org (cherry picked from commit a1037f203c6a07cb116eeb1632cb7200ad022cd3)
This cherry-pick was modified to match the tegra124 uart.c, which uses the idx and base address calculations instead of Kconfig settings. This driver could use the 8250MEM driver when the ARM vs x86 IO calling convention is worked out.
