[Qemu-devel] [PATCH] pc/acpi: Fix booting of macOS with Clover EFI bootloader

[Dhiru Kholia <dhiru.kholia@gmail.com>]

This was tested with macOS 10.12.5 and Clover r4114.

Without this patch, the macOS boot process gets stuck at the Apple logo
without showing any progress bar.

I have documented the process of running macOS on QEMU/KVM at,

https://github.com/kholia/OSX-KVM/

Instead of using this patch, adding an additional command-line knob
which exposes this setting (force_rev1_fadt) to the user might be a more
general solution.
