* TODO: Add note about endianness in grub-mkimage. * boot/powerpc/ieee1275/crt0.S (note): Remove unused .note section. * conf/powerpc-ieee1275.rmk (bin_UTILITIES): Add grub-mkimage. (grub_mkimage_SOURCES): New target. * include/grub/kernel.h (grub_start_addr): Remove variable. (grub_end_addr): Likewise. (grub_total_module_size): Likewise. (grub_kernel_image_size): Likewise. (GRUB_MODULE_MAGIC): New constant. (grub_module_info): New structure. (grub_arch_modules_addr): New prototype. (grub_get_end_addr): Remove prototype. * include/grub/i386/pc/kernel.h (grub_end_addr): New prototype. * include/grub/powerpc/ieee1275/kernel.h: New file. * include/grub/util/misc.h (grub_util_get_fp_size): New prototype. (grub_util_read_at): Likewise. (grub_util_write_image_at): Likewise. * kern/main.c (grub_get_end_addr): Remove function. (grub_load_modules): Call grub_arch_modules_addr instead of using grub_end_addr. Look for a grub_module_info struct in memory. Use the grub_module_info fields instead of calling grub_get_end_addr as loop conditions. Move grub_add_unused_region code here. (grub_add_unused_region): Remove function. * kern/i386/pc/init.c: Include grub/cache.h. (grub_machine_init): Remove call to grub_get_end_addr. Remove one call to add_mem_region.

(grub_arch_modules_addr): New function. * util/misc.c: Include unistd.h. (grub_util_get_fp_size): New function. (grub_util_read_at): Likewise. (grub_util_write_image_at): Likewise. (grub_util_read_image): Call grub_util_read_at. (grub_util_write_image): Call grub_util_write_image_at. * util/i386/pc/grub-mkimage.c (generate_image): Allocate additional memory in kernel_img for a struct grub_module_info. Fill in that grub_module_info. * util/powerpc/ieee1275/grub-mkimage.c: New file.
