Please see my reply to your previous mail.

Each of these enumerations has at least one concrete component in
base/include/drivers or base-hw/ that depends on it. Separating these
values from e.g. the device drivers came due to the fact that they do
not depend on the device specification but on the board that integrates
the device. For instance you might want to reuse the PL011 timer but
different boards integrate it with a different clock or interrupt number
(see base/include/platform/rpi/drivers/board_base.h and
base/include/platform/pbxa9/drivers/board_base.h). A board might even
integrate multiple PL011 chips with different values (see PBXA9).
