DESCRIPTION

This file contains the Board-Specific Vital Product Data utility routines.

CAVEATS
These routines are needed before the kernel is un-compressed. For proper
operation, this file must be added to the BOOT_EXTRA list in the Makefile to
prevent it from being compressed during kernel generation.
