From: Andreas Fritiofson Date: Fri, 13 Nov 2015 23:51:40 +0000 (+0100) Subject: arm_adi_v5: Add a back-pointer from an AP to its DAP X-Git-Tag: v0.10.0-rc1~316 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=5ae2fbda2b8744752f9a8d5dbdb0090df812a894;p=openocd arm_adi_v5: Add a back-pointer from an AP to its DAP This will make it possible to reference directly the AP used for debug in the target instance and remove the DAP reference. This will in turn enable getting rid of the need to select an "active" AP in the DAP (using dap apsel).
