commit 0f76bda638538c2ca932d3b8ca752cf41f72c1a1 Author: Gabe Black gabeblack@google.com Date: Fri Aug 9 00:31:09 2013 -0700
exynos5420: Configure the UART pins unconditionally
Configure the pins for the UART unconditionally in the mainboard code (when we know which UART to configure) instead of in the UART driver. This also means the UART will work if later software wants to use it without setting up the pins.
Built and booted on pit with the serial turned off and some serial init in the kernel decompression stub fixed.
