Yes, I think we would need a cbfs file for allocating the region before hand and then that would be used by ERST and pstore. I don' t know how the region internals work. Also, there are problaly some pstore limitation and knowing the flash device before hand to set alignment (erase blocks) etc. Marc -- http://se-eng.com -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
