This patch makes the handling of the initrd (or initramfs) in the zImage wrapper a little easier to follow. Instead of passing the initrd addresses out from prep_kernel() via the cryptic a1 and a2 parameters, use the global struct add_range, 'initrd'. prep_kernel() already passes information through the 'vmlinux' addr_range struct, so this seems like a reasonable extension. Some comments also clarify the logic with prep_kernel(): we use an initrd included in the zImage if present, otherwise we use an initrd passed in by the bootloader in the a1 and a2 parameters (yaboot, at least, uses this mechanism to pass an initrd).
