-/*
- * Read a factory.rom dump (ich9m/gm45 systems) and
- * modify the flash descriptor to remove all regions except descriptor,
- * Gbe and BIOS. Set BIOS region to full size of the ROM image (after
- * the flash descriptor and gbe). Basically, deblob the descriptor.
- *
- * This will will generate a concatenated descriptor+gbe dump suitable
- * for use in libreboot. Currently tested: ThinkPad X200 (coreboot/libreboot)
