From 17921f51abc4402c9c5aadf3e664eb37663f744f Mon Sep 17 00:00:00 2001 From: David Brownell Date: Thu, 7 Jan 2010 15:52:38 -0800 Subject: ARMv7: help/usage updates Provide helptext which was sometimes missing; update some of it to be more accurate. Usage syntax messages have the same EBNF as the User's Guide; there should be no angle brackets in either place. Don't use "&function"; functions are like arrays, their address is their name. Shrink some overlong lines, remove some empties. Add a couple comments about things that should change: those extra TCK cycles for MEM-AP reads are in the wrong place (that might explain some problems we've seen); the DAP command tables should be shared, not copied.
