From: Vineet Gupta Date: Sat, 5 Apr 2014 10:00:22 +0000 (+0530) Subject: ARC: [nsimosci] Unbork console X-Git-Tag: firefly_0821_release~176^2~4109^2 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=61fb4bfc010b0d2940f7fd87acbce6a0f03217cb;p=firefly-linux-kernel-4.4.55.git ARC: [nsimosci] Unbork console 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.
