There is some question as to the legal status of re-using tables - in the absence of any clear legal guidance I think that we should err on the side of safety and not allow tables from commercial BIOSen.
It wont work because lot of I/O resources is static in the ACPI. Creating some minimalistic ACPI tables should not be too difficult.

I added basic support to create a TCPA ACPI table. The TCPA table have 2 specific fields : log_address and max_log_length. The log address should point to a buffer of max_log_length bytes (0x10000 in my case) in the ACPI Non-volatile Storage.
I guess this is the responsability of coreboot to reserve a portion of RAM for the ACPI NV Storage. I'm interested in adding this functionnality in coreboot but how usefull is it ?
