From 71dccd0f158a8077c92d51f213b55991b7a0e47e Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 16 Mar 2006 20:50:34 +0000 Subject: [PATCH] [ARM] Collect Primecell PL01x-based debug implementations together Several ARM machine implementations used a PL01x primecell compatible serial port for debugging purposes, and indepdently implemented the low level debug macros every time. Provide a common implementation and convert these implementations to use this version.
