ACPI / tables: table override from built-in initrd
In some scenario, we need to build initrd with kernel in a single image. This can simplify system deployment process by downloading the whole system once, such as in IC verification. This patch adds support to override ACPI tables from built-in initrd. Signed-off-by: Shunyong Yang <shunyong.yang@hxt-semitech.com> [ rjw: Minor cleanups ] Signed-off-by: Rafael J.
