Common Firmware Environment (CFE), sometimes pronounced as 'cafe', is a firmware interface and bootloader developed by Broadcom for 32-bit and 64-bit system-on-a-chip systems. It is intended to be a flexible toolkit of CPU initialization and bootstrap code for use on embedded processors (typically running on MIPS32/64 instruction set CPUs found in Broadcom SoCs). It is roughly analogous to the BIOS on the IBM PC platform. Its source-code is available on Open source license from Broadcom. Common embedded system alternatives include Das U-Boot.
