From 867ac1370b294bfd1ee31f94abb63688f77081a1 Mon Sep 17 00:00:00 2001 From: Alistair Francis Date: Tue, 21 Nov 2017 16:43:57 -0800 Subject: runqemu: Allow the user to override the device tree option Update the runqemu script to allow the user to specify a device tree to boot when calling runqemu. This involves creating a seperate check_dtb() function incase the user has specified 'none' for the kernel but still wants a device tree.
