From fd14750345ef7e4a543b9da18000de9a18e3439a Mon Sep 17 00:00:00 2001 From: Tom Zanussi Date: Tue, 24 Jan 2012 11:40:29 -0600 Subject: meta-crownbay: update README The new emgd-driver-bin_1.10 recipe no longer requires manually extracting and installing emgd binaries, so remove the section that deals with that. It does require a new LICENSE_FLAGS_WHITELIST entry in local.conf, so add instructions detailing that.
