I know of a board manufacturer (who shall go unnamed here)  who  uses
the  following  procedure  to (re-) install U-Boot in flash: unsolder
the flash chips, re-ball the BGAs, reprogram the chips in a  standard
flash programmer, re-solder. They think this is cheaper than buying a
JTAG debugger... [No smiley here; guess why.]
