* boot/powerpc/ieee1275/cmain.c (module_info): Remove definition. (grub_ieee1275_chosen): New variable. (cmain): Initialize and use `grub_ieee1275_chosen' instead of `chosen'. * boot/powerpc/ieee1275/crt0.S (init_stack): Remove stack space. * boot/powerpc/ieee1275/ieee1275.c (grub_ieee1275_get_property): Rename first argument to `phandle' for consistency. (grub_ieee1275_get_property_length): Likewise. (grub_ieee1275_next_property): Likewise. Change type of first argument to grub_ieee1275_phandle_t. * include/grub/powerpc/ieee1275/ieee1275.h (grub_ieee1275_entry_fn): Move export next to declaration. (grub_ieee1275_chosen): New variable. * include/grub/powerpc/ieee1275/kernel.h (GRUB_IEEE1275_MODULE_BASE): Correct cosmetic typo. * kern/powerpc/ieee1275/init.c (grub_set_prefix): Use `grub_ieee1275_chosen'. * kern/powerpc/ieee1275/openfw.c (grub_map): Likewise. * loader/powerpc/ieee1275/linux.c (grub_linux_boot): Likewise. (grub_rescue_cmd_linux): Set `initrd_addr' to 0. * term/powerpc/ieee1275/ofconsole.c (grub_ofconsole_refresh): Use `grub_ieee1275_chosen'.
