From 91fe8b79f6912ab7622169bc1673e2df222e0b57 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 8 Apr 2020 16:57:38 -0600 Subject: acpi: Add a central location for table version numbers Each ACPI table has its own version number. Add the version numbers in a single function so we can keep them consistent and easily see what versions are supported. Start a new acpi_table file in a generic directory to house this function. We can move things over to this file from x86 as needed.
