Subject: [PATCH v7 08/22] arm/acpi: Prepare RSDP table for Dom0
Date: Fri, 25 Mar 2016 21:48:41 +0800 [thread overview]
Message-ID: <1458913735-2678-9-git-send-email-shannon.zhao@linaro.org> (raw)
In-Reply-To: <1458913735-2678-1-git-send-email-shannon.zhao@linaro.org>
Copy RSDP table and replace rsdp->xsdt_physical_address with the address
of XSDT table, so it can point to the right XSDT table.
