The ACPI APIE and ERST methods allow the kernel to mount pstore to store information in NVRAM (coreboot cbfs). This could be used to store errors that are otherwise difficult to track, like suspend and resume issues. The implementation would need to be able to find an area free in cbfs for storing the data.
Reserve it beforehand? That's what I intend to do for Tiano variables
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.
