AMD boards: ACPI DSDT: Use COREBOOT for the OEM Table ID field
The DSDT header contains the fields OEMID and OEM Table ID. See
for example ACPI specification 4.0a 
184.108.40.206 Differentiated System Description Table (DSDT)
on page 135. There Table 5-16 contains the descriptions.
Field Byte Length Byte Offset Description
OEMID 6 10 OEM ID
OEM Table ID 8 16 The manufacture model ID.
Currently in coreboot there is no common method what to put in
Mostly Intel based boards populate it with "CORE " ore "COREv4"
and AMD based boards populate it with the board vendor and
model number, abbreviated appropriately to fit into these fields.
On most boards the proprietary vendor BIOS seems to leave these
fields – displayed with `sudo dmidecode` under System Information –
To Be Filled By O.E.M.
and fill out the Base Board Information with the board vendor and
In  Jens Rottmann argues that the this is really just the table
ID used for naming it and that »99% of the DSDT code is not board
Both approaches seem to have their advantages, but using the
second one, developers often seem to forget to update them (for
example AMD Thather).
The current situation is at least not optimal. and therefore at
least unify the string in the OEM Table ID. If unifying the
OEM ID is also a good idea this should be done too.
If later on it should be decided that the board vendor and model
should be used again, this should be somehow derived from
The following command was used for the change .
$ git grep -l '\/\* TABLE ID \*\/' | xargs sed -i '/TABLE ID/s/"\([^"]*\)"/"COREBOOT"/'
