It is not part of U-Boot, but is definitely related.
It is a utility which resided in the first sector(s) of a dataflash or NAND 
flash.
At reset, the AT91 bootROM loads this into internal SRAM and jump to the
beginning of the SRAM, starting executing at91-bootstrap.

At91-bootstrap configures the DRAM memory and a few other things
and then loads U-Boot from data/NAND flash to SDRAM
and starts executing U-Boot.
Reason for not putting this inside the U-Boot is that due to H/W
restrictions (internal SRAM size), the max size of the program is 4 kB.

There is a lot of AT91/U-Boot users, having
problems with having to have a special compiler
for this little application, so I thought they would be interested.

It could of course be in the tools directory.
