From d33a81c549743e13633db9e8749f0e7cb0f7324b Mon Sep 17 00:00:00 2001 From: David Brownell Date: Fri, 5 Mar 2010 10:39:25 -0800 Subject: ADIv5 share DAP command support Get rid of needless and undesirable code duplication for all the DAP commands (resolving a FIXME) ... there's no need for coreas to have private copies of that stuff. Stick a pointer to the DAP in "struct arm", letting common code get to it. Also rename the "swjdp_info" symbol; just call it "dap". This is an overall code shrink.
