From 34a6d0b84a25a141123f589b0cfef2bf88afe220 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Fri, 29 Apr 2011 23:10:54 -0400 Subject: [PATCH] Blackfin: uart: move debug buffers into local bss There's no need for these saved buffers to be global symbols, or in the data section. So mark them static to move them into the bss.
