soc/amd/stoneyridge: Name IO061 in ASL appropriately
AMD traditionally claims the resource at I/O port 61 for the onboard PC-AT speaker. In later designs, the speaker may be omitted in favor of routing the SPKR signal to the codec. Some systems implement neither, and for those it is not correct to identify the resource as a speaker. Modify the EISAID reported to the OS depending on the system design. The default is that port 61 is reported as reserved. In order to report a speaker, add #define in mainboard//dsdt.asl. TEST=check /proc/ioports and iasl -d for both ways using a Grunt BUG=b:117818432 Change-Id: I33aafb187f9fea7b38aae43c399292c7521fcfc4 Signed-off-by: Marshall Dawson <marshalldawson3rd@gmail.com> Reviewed-on: https://review.coreboot.org/c/30037 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Martin Roth <martinroth@google.com>
