This patch makes the following changes:
- Set kernel entry point correctly
- Append bootargs from image to global bootargs instead
of replacing them
- Return end address instead of size from android_image_get_end()
- Give correct parameter to genimg_get_format() in boot_get_ramdisk()
- Move ramdisk message printing from android_image_get_kernel() to
android_image_get_ramdisk()
