Harmonize ieee1275's grub_available_iterate() with the generic
grub_machine_mmap_iterate() interface (fixes a recently-introduced
build problem on i386-ieee1275):
* kern/ieee1275/openfw.c (grub_available_iterate): Moved from here ...
* kern/ieee1275/mmap.c (grub_machine_mmap_iterate): ... here. Add third
parameter `type'. Update all users of this function.
* conf/i386-ieee1275.rmk (kernel_elf_SOURCES): Add
`kern/ieee1275/mmap.c'.
* kern/ieee1275/init.c
* include/grub/ieee1275/ieee1275.h (grub_available_iterate): Replace
with ...
(grub_machine_mmap_iterate): ... this.
* include/grub/i386/pc/memory.h (grub_machine_mmap_iterate): Change
return type to `grub_err_t'. Update all implementations of this
function prototype.
* include/grub/i386/coreboot/memory.h (grub_machine_mmap_iterate):
Likewise.
