From ea7a49cb9b46ccc27daf6c9b306290c7e905a9fc Mon Sep 17 00:00:00 2001 From: David Brownell Date: Thu, 3 Dec 2009 16:08:04 -0800 Subject: ARM DPM: share debug reason logic No point in both ARM11 and Cortex-A8 having private copies of the logic sorting out e.g. DBG_REASON_WATCHPOINT. Add and use a shared routine for this ... there's actually a bunch more debug entry logic that could be shared, this is just a start on that. Note that this routine fixes a bug observed in the ARM11 code, where some abort mode quirks were displayed as being an unknown debug reason; and also silences needless ARM11 chatter. Likewise with private copies of DSCR ... add one to the DPM struct. Save it as part of setting DBG_REASON_* so later patches can switch over to using that copy.
