The Common Firmware Environment (CFE) is designed to be easily portable to designs incorporating current
and future Broadcom MIPS64-compatible broadband processors. Supported platforms include Broadcom’s
SiByte processor family (containing the BCM1250, BCM1125H, and other processors), 32-bit and 64-bit
memory models, and big and little-endian operation. There are many parameters configurable at build time that
can be used to customize CFE to suit diverse customer requirements.
On the BCM91125E, CFE can load programs (such as S-records, raw binary, or ELF formatted) from bootstrap
devices in a variety of ways, including:
•
Via either Ethernet port, from a TFTP server
•
Via the serial port (S-records only)
For additional information on CFE, refer to the
Common Firmware Environment (CFE) Specification document
that can be found in the CFE source code distribution at: http://sibyte.broadcom.com/public.
