Flash ROM Recovery Mechanism

The IPMC provides a Flash ROM recovery mechanism that supports booting IPMC FW from a
fail-safe location in case the content of the firmware flash inside the IPMC (Image A) is
corrupted.

The IPMC controller chip has a Boot Loader that resides on the on-chip flash. The Boot Loader
can determine the validity of FW Image A. The Boot Loader is programmed in manufacture and
will not be changed by design. The ATCA-7350 provides an external Flash chip for the IPMC,
which stores the FW Image B and FW Image C.
