runqemu: standardize ability to specify custom qemu/kenel boot options
The old manner of specifying custom options to QEMU in this script using angle brackets was a frequent source of confusion. Meanwhile, Otavio Salvador added a decent method of specifying custom kernel boot options to this script. This patch documents the bootparams option and adds a similar way of specifying custom QEMU options using qemuparams="". This fixes [YOCTO #1019] Signed-off-by: Scott Garman <scott.a.garman@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
