at91bootstrap: New package at91bootstrap
at91bootstrap is a second-level bootloader for Microchip(Atmel AT91) SoCs.
It provides a set of algorithms to manage the hardware initialization and
to download the main application or a third-level bootloader(i.e. uboot)
from specified boot media to main memory and execute it.
