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. Best Regards Ulf Samuelsson
