commit 103dbbb9059cda440d8f54e851677eeaae9df6a1 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.
