If the dtb passed to the kernel is non-empty then device-tree + will be chosen as the boot method of choice. + + RHEL does not wish to support this boot method so change table boot + preferences to use ACPI. In the event ACPI table checks fail the kernel + will fallback to using DTS to boot. + + Signed-off-by: Jonathan Toppins + +Upstream Status: RHEL only +Signed-off-by: Mark Salter +Signed-off-by: Herton R.
