[ECOS] corrupt fis detection

we are erasing the fis block from linux kernel and rewritting it with
new information every time on a successfull boot up.

In case of power failure, this I realise opens up a window of error.
Between erase and final write if power reset happens. 
Can we be sure that fis will detect that its an unprogrammed fis and act ?
how does redboot detect that fis is blank, some magic number etc ?

Can we be sure that redboot will atleast not get screwed in reading
half cooked information ?

any other way to do this ?
