limitations mips-loongson (with Linux protocol)
and mips-qemu_mips can use only memory up to first hole.
Bootlocation is ability of GRUB to automatically detect where it boots from.
``disk'' means the detection is limited to detecting the disk with partition
being discovered on install time. ``partition'' means that disk and partiton
can be automatically discovered. ``file'' means that boot image file name as
well as disk and partition can be discovered. For consistency default install ignores
partition and relies solely on disk detection. If no bootlocation discovery is available
or boot and grub-root disks are different, UUID is used instead. On ARC if no device
to install to is specified, UUID is used instead as well.
