[Qemu-devel] [PULL v3 29/44] hw: acpi: Remove AcpiRsdpDescriptor and fix tests |
Date: |
Thu, 20 Dec 2018 13:39:47 -0500 |
From: Samuel Ortiz <address@hidden>
The only remaining AcpiRsdpDescriptor users are the ACPI utils for the
BIOS table tests.
We remove that dependency and can thus remove the structure itself.
