Also, if loaded at address 0, U-Boot will partially overwrite the uImage because of a bug in get_ram_size() (U-Boot v2015.10) not restoring properly the probed RAM contents and because the exception vectors are installed in the same range. Finally, a gzipped kernel image will be uncompressed at 0x0. These are all good reasons for not mappping a kernel image at this address. Change the kernel load address to match U-Boot expectations and fix loading.

But, it's not that simple because the CPU still starts at address 0xfffffffc where nothing is currently mapped. Support must have been broken these last years. Since we can not find a "ppc405_rom.bin" firmware file, request one to be specified on the command line. A consequence of this change is that the machine can be booted directly from Linux without any FW being loaded. This is still broken and the CPU start address will be fixed in the next changes.

Change the QEMU PPC405 board information to match the hotfoot board and let the ref405ep machine boot from Linux directly. Only the CPU frequency is required. This is brutal force. We could possibly add a machine option or a ref405ep machine class to update the board information accordingly. A similar change would be required in U-Boot. The alternative is to change Linux.
