It is easy to postulate requirements. But seriously, if you are
careless enough to use flash chips which can change modes or even
lose data by just writing random data to sequential addresses then
you must also accept the consequences. Either provide adequate
recovery mechanisms in Linux or your OS of choice or in U-Boot.
I have to admit that I fail to understand what exactly your problem
is: if you want to use the hardware protection features in U-Boot
(including the unlocking of locked sectors) then just enable this
feature in U-Boot.
Best regards,

Nobody goes to that restaurant anymore. It's too crowded.
