Changes: (1) register pstrcpy_targphys() in rom list, it is used for kernel command lines by a number of architectures. (2) add rom_ptr() function to get a pointer for applying changes to loaded images. Needed for example to tell the linux kernel where it finds the initrd image by updating the header. (3) make sparc use rom_ptr for initrd setup. booting sparc-test works now, and 'info roms' shows this: (qemu) info roms addr=0000000000000000 size=0x2a3828 mem=ram name="phdr #0: vmlinux-2.6.11+tcx" addr=00000000007ff000 size=0x00000e mem=ram name="cmdline" addr=0000000000800000 size=0x400000 mem=ram name="/root/qemu-test/sparc-test/linux.img" addr=0000000070000000 size=0x0e4000 mem=rom name="phdr #0: /home/kraxel/projects/qemu/build-zfull/pc-bios/openbios-sparc32" reboot via 'system_reset' works too.
