Subject: [kvm-unit-tests PATCH v5 11/18] powerpc/ppc64: add a boot rom
Date: Wed, 17 Feb 2016 19:40:52 +0100 [thread overview]
Message-ID: <1455734459-31902-12-git-send-email-drjones@redhat.com> (raw)
In-Reply-To: <1455734459-31902-1-git-send-email-drjones@redhat.com>
Make a one line replacement for SLOF. This bootloader just
jumps to 0x400000, because we know the kernel will be there.
