From 0170804f60b19a2033ac39964fcd192a0c7eda42 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 25 Jul 2016 18:59:13 -0600 Subject: dtoc: Move to using bytearray Since we want to be able to change the in-memory device tree using libfdt, use a bytearray instead of a string. This makes interfacing from Python easier.
