From: David Brownell Date: Tue, 17 Nov 2009 00:36:09 +0000 (-0800) Subject: ARM: "armv4_5" command prefix becomes "arm" X-Git-Tag: v0.4.0-rc1~551 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=f86137066a6b42c46c457c9837a8015990bf71e6;p=openocd ARM: "armv4_5" command prefix becomes "arm" Rename the "armv4_5" command prefix to straight "arm" so it makes more sense for newer cores. Add a simple compatibility script. Make sure all the commands give the same "not an ARM" diagnostic message (and fail properly) when called against non-ARM targets.
