The objective of this project is to provide an SDK and root file system for the Raspberry Pi that is lightweight and takes full advantage of the hardware available. The resulting image produced is small distro known as Bsquask (linux). The Bsquask SDK provides a GCC 4.6.3 toolchain for building armv6 binaries with the hardfloat ABI, as well as bootloaders, kernel image, rootfs, and development sysroot for the Raspberry Pi. - VideoCore Tools · nezticle/RaspberryPi-BuildRoot Wiki
