From 3c65677ba6f1e946a8294a2bcf89990aa8dccc59 Mon Sep 17 00:00:00 2001 From: Andreas Fritiofson Date: Sat, 5 Oct 2013 00:24:28 +0200 Subject: [PATCH 1/1] lpc288x: Can now use target_write_buffer() Use the preferred code path according to the comment. Target_write_buffer() now simply uses suitably aligned target_write_memory calls, so from this pov, they should be equivalent.
