From 11a0f40bc98d6ae34cb3283e6008abc433e252bb Mon Sep 17 00:00:00 2001 From: Alban Bedel Date: Fri, 7 Nov 2014 12:44:35 +0100 Subject: MIPS: ath79: Use the firmware lib to parse the kernel command line No need to duplicate code that is available in the firmware library. It also give us access to the firmware environment which is needed to read the initrd address and size.
