From f0cdbdd6d8ada085199e6250cbf3b7fbe69392ac Mon Sep 17 00:00:00 2001 From: Alexey Galakhov Date: Fri, 8 Feb 2013 13:44:43 -0800 Subject: [PATCH] ARM: S5PV210: Fix early uart output in fifo mode Enabling UART FIFO in bootloader caused the kernel infinite loop on S5PV210 due to uninitialized fifo_max and fifo_mask global variables. This patch adds the correct initialization.
