PPCBoot

The Embedded PowerPC Linux Boot Project (PPCBOOT) has implemented a common and easily extensible boot program for embedded devices. The entire project source code is released under the GNU General Public License (GPL), and takes advantage of an open development process at SourceForge.net, the highly popular portal of open source software development.

Over time, the name PPCBoot has become inappropriate: we don't exclusively support PowerPC CPUs. There is also support for a couple of ARM7, ARM9, StrongARM and XScale based board. Ports for ColdFire and even x86 are in the planning or already under way. Thus it's time to acknowledge that this project has become a universal bootloader - we will continue development under the new flag U-Boot - the Universal Boot Loader
