From 40f4d61266192f2ec439c943be7a945232efd388 Mon Sep 17 00:00:00 2001 From: Randall Spangler Date: Wed, 11 Sep 2013 16:18:50 -0700 Subject: Remove unused uart functions Nothing ever called uart_flush_input() or uart_gets(), so remove them. They're dead code, and make implementing UART DMA input more complex.
