From 4e56a2303b3f68bb647d8bb640a830f7f21ea231 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Fri, 27 Nov 2009 18:50:20 -0800 Subject: target: groundwork for "reset-assert" event This defines a "reset-assert" event and a supporting utility routine, and documents both how targets should implement it and how config scripts should use it. Core-specific updates are needed to make this work.
