To initialize the hardware and run (boot) the operating system of your 
choice.  The board's CPU runs u-boot code from the release of reset 
until the CPU jumps to the OS code (often linux).

The above is only a fraction of what u-boot _can_ do, but is the primary 
(original?) reason for its existence.
