No, not exactly.  We can boot these devices using ACPI, but with
limited functionality (when compared with booting using DT).  There
are too many black-boxes when booting with ACPI - something that can
only be resolved with Qualcomm's help.

Booting with ACPI helps us to use generic Linux distribution
installers, but it is expected for users to switch to DT once the OS
is installed.
