[Qemu-arm] [PULL 31/55] acpi: support specified oem table id for build_header |
Date: |
Tue, 22 Dec 2015 18:54:08 +0200 |
From: Xiao Guangrong <address@hidden>
Let build_header() support specified OEM table id so that we can build
multiple SSDT later
If the oem table id is not specified (aka, NULL), we use the default id
instead as the previous behavior
