hw/ppc/epapr: Do not swap ePAPR magic value
The ePAPR magic value in $r6 doesn't need to be byte swapped. See ePAPR-v1.1.pdf chapter 5.4.1 "Boot CPU Initial Register State" and the following mailing-list threads: https://lore.kernel.org/qemu-devel/CAFEAcA_NR4XW5DNL4nq7vnH4XRH5UWbhQCxuLyKqYk6_FCBrAA@mail.gmail.com/ https://lore.kernel.org/qemu-devel/D6F93NM6OW2L.2FDO88L38PABR@gmail.com/ Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> Reviewed-by: Nicholas Piggin <npiggin@gmail.com> Tested-by: BALATON Zoltan <balaton@eik.bme.hu> Reviewed-by: Harsh Prateek Bora <harshpb@linux.ibm.com> Message-ID: <20241220213103.6314-7-philmd@linaro.org> Signed-off-by: Nicholas Piggin <npiggin@gmail.com>
