From ea85ed98beb909d9295a7b15ceb99e067082e31f Mon Sep 17 00:00:00 2001 From: Paul Fertser Date: Mon, 9 Mar 2015 18:55:03 +0300 Subject: [PATCH] jtag/core: honour SRST timings in SWD mode Since SWD is currently abusing the JTAG command queue for reset and sleep handling (and all other operations are performed in a different way), sleep needs to be forced explicitly to ensure correct timings.
