From c02bda0f066927744c5d75de14e4c1cf73ce39c9 Mon Sep 17 00:00:00 2001 From: Patrick Rudolph Date: Fri, 28 Feb 2020 10:19:41 +0100 Subject: acpi: Bump FADT to revision 6 Some of the revision 4 FADT fields were already updated to ACPI spec revision 6, but not all of them. In addition the advertised FADT revision was 3. Implement all fields as defined in version 6 and bump the advertised FADT revision to 6. Also set all used access_size fields and x_gpe0_blk to sane values as Windows 10 verifies those fields starting with FADT revision 5. Fixes: https://ticket.coreboot.org/issues/109 Tested on Windows 10.
