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 from hard
disk on reset, which could make loader framework more dynamic and
reduce the memory consumption of QEMU process.
Olivia Yin (3):
use image_file_reset to reload initrd image
use uimage_reset to reload uimage
use elf_reset to reload elf image

v4:
uImage/vmlinux/ramdisk had been verified on PowerPC platforms.
Issue:
It seemed that the patch 3/3 could not free the memory for phdr, and the
memory map of QEMU will increase 1392K every time.
If free phdr, system_reset will cause segmentation fault.
