#     powerpc/kexec_file: Enable early kernel OPAL calls
#     
#     Kernels built with CONFIG_PPC_EARLY_DEBUG_OPAL enabled expects r8 & r9
#     to be filled with OPAL base & entry addresses respectively. Setting
#     these registers allows the kernel to perform OPAL calls before the
#     device tree is parsed.
