This bootstrap package is required on at91sam* boards where dataflash/nandflash
is used to boot from. In these cases the internal bootROM of the AT91 core is
used to boot the board with.
Patch Version 2:
* Cleanup of Kconfig files
* Added patch to align U-boot load addr to dataflash sector boundaries
This is what mainline U-boot demands, and what clearly is a bug in the
original Atmel's Bootstrap code.
* Added Kconfig option for selection between dataflash and nandflash
* Upgraded template of Makefile.

+ help
+ The AT91Bootstrap application is a first level bootloader
+ for Atmel AT91SAM9 ARM Thumb-based microcontrollers.
+ AT91Bootstrap also provides examples, for a particular device, on
+ how to perform basic static configurations, such as PMC and
+ PIOs.
+ AT91Bootstrap integrates several sets of algorithms:
+ - Device initialization such as clock speed configuration,
+ PIO settings, etc.
+ - Peripheral drivers such as PIO, PMC, SDRAMC, etc.
+ - Physical media algorithms such as DataFlash, NANDFlash, etc.
+ For example, using this set of algorithms, it is possible to
+ obtain a basic bootloader that is located in DataFlash and is
+ copied to internal SRAM by SAM-BA Boot. The bootloader performs
+ the processor initialization (PLLs, PIOs, SDRAMC, SPI), loads UBoot
+ from DataFlash sectors to SDRAM and then jumps to it.
