U-Boot
Many modern boards and ARM-based systems come with U-Boot. Something like the first-level bootloader described above often runs first, and gets the low-level hardware (clocks and ram) running enough to load and launch u-boot. U-boot can be customized with support for a wide variety of storage systems, network interfaces, filesystems, and even utilities to test and format hardware devices and copy data to them.
Generally you need a copy of u-boot that has been customized and compiled for your particular chip and board.
