[PATCH 3/7] ppc/pnv: Use skiboot addresses to load kernel and ramfs |

The current settings are useful to load large kernels (with debug) but
it moves the initrd image in a memory region not protected by
skiboot. If skiboot is compiled with DEBUG=1, memory poisoning will
corrupt the initrd.

If we want to increase the kernel size limit as commit b45b56baeecd
("ppc/pnv: increase kernel size limit to 256MiB") intented to do, I
think we should add a machine option.
