From d6253caaa1a6cc9cf8ca624006872e9dcda13e15 Mon Sep 17 00:00:00 2001 From: Vincent Palatin Date: Fri, 29 Aug 2014 14:19:43 -0700 Subject: CHERRY-PICK: Allow to disable default DMA interrupt handlers The default DMA interrupt handlers are somewhat slow and not really flexible, allow to override them in board if needed.
