[U-Boot-Users] flash protection code in cfi_flash

[David Ho]

If anyone is working on Intel non-J3 flashes.  This should be of interest.

Unprotecting all flash blocks on a 64MB K3 flash, in msecs.

My board takes an additional 2 seconds to boot as a result, because
the board comes up with all blocks locked.
