The current model of loader copy "rom blobs" and kept in memory until a reset
occurs and waste host memory.
This serial of patches uses private reset handlers to load uimage/initrd/vmlinux
from hard disk on reset, which could make loader framework more dynamic and
reduce the memory consumption of QEMU process.
Olivia Yin (4):
use image_file_reset to reload initrd
use uimage_reset to reload uimage
use elf_reset to reload elf image
free rom->data when rom_reset
