i am asking about possibility that in function 'write_buff' there is no checking of protect[] status...so how to get sure that over uboot sector is protected or not???

your summary doesn't seem to match the actual question here ... what does this have to do with POST (which already has a parallel nor flash test) ?

as for the question, i recall u-boot issuing a "skipping protected sectors" type message, so you might want to grep for that and then start your code search from there. -mike
