From 263296e549455afa1484cf9dec75fc3014a83954 Mon Sep 17 00:00:00 2001 From: Antonio Borneo Date: Mon, 3 Feb 2020 10:02:54 +0100 Subject: [PATCH] jtag: flush queue after reset for drivers using old reset model Not all the jtag drivers have been migrated to the new reset model and for those only we need to flush the jtag queue to make the reset working with command 'adapter [de]assert ...'. Add a queue flush and a FIXME comment to remove both when all the drivers would be migrated.
