Hi,

Thank you for your reply.

This corresponds to CGL Availability Requirements Definition V4.0: AVL.9.1, 
whereas Boot Image Fallback is AVL.9.0.
(http://developer.osdl.org/dev/cgl/cgl40/cgl40-availability.pdf)
Boot Image Fallback must handle not only image CRC error before kernel boot, 
but a boot failure like kernel panic during kernel boot process (after image 
has successfully loaded). Also, it must fallback after power-on reset.
