SUMMARY = "Initial bootstrap for AT91 ARM MPUs"
DESCRIPTION = " \
		at91bootstrap is the second-level bootloader for 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) from specified boot media to         \
		main memory and start it.                                    \
