From: Vineet Gupta Date: Sat, 5 Apr 2014 10:00:22 +0000 (+0530) Subject: ARC: [nsimosci] Unbork console X-Git-Url: http://git.mmlx.us/?a=commitdiff_plain;h=47c4534a109e45700d1d1c8467c2b5a618212d81;p=linux-edison.git ARC: [nsimosci] Unbork console commit 61fb4bfc010b0d2940f7fd87acbce6a0f03217cb upstream. Despite the switch to right UART driver (prev patch), serial console still doesn't work due to missing CONFIG_SERIAL_OF_PLATFORM Also fix the default cmdline in DT to not refer to out-of-tree ARC framebuffer driver for console.
