This is a TFFS socket driver to support the LAT SIB board. Each SIB provides two EEPROM banks. Each bank is mapped twice. The more familiar mapping is the "/ee" mapping which is later fomatted and mounted as a TFFS file system. The second mapping overlays the "boot" section of the "/ee" mapping, providing memory access to the boot partition after the "/ee" mapping is mounted.

Support for the SIB hardware level write locks (one per bank) is provided by the sibVppOn() and sibVppOff() routines.

Warning:

While other parts of the code continue to support the "SIB evaluation board", the routines in this file do not.
