X-Git-Tag: v2022.07~208^2~88
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e1722fcb7d3fcb62b41f0feda4ac2c7d27d7c1f1;p=platform%2Fkernel%2Fu-boot.git

x86: Allow any arch to generate ACPI tables

These have sadly found their way to ARM now. Allow any arch to support
generating ACPI tables.

Disable this for the tools build.
