Subject: [PATCH v1 1/2] MdePkg: Add ACPI 6.5 header
Date: Tue, 17 Jan 2023 20:55:37 +0800	[thread overview]
Message-ID: <20230117125538.4172645-2-lichao@loongson.cn> (raw)
In-Reply-To: <20230117125538.4172645-1-lichao@loongson.cn>

Create Acpi65.h, which is copied from Acpi64.h, and make the following
changes:

1. Replace all occurences of "6.4/6_4" with "6.5/6_5".
2. Incremented FADT minor revision.
3. Make Acpi65.h the latest ACPI definitions that Acpi.h contains.
