details:   https://anonhg.NetBSD.org/src/rev/e0fc4b4fa24e
branches:  trunk
changeset: 977604:e0fc4b4fa24e
user:      jdc <jdc%NetBSD.org@localhost>
date:      Thu Oct 29 06:47:38 2020 +0000

description:
Add information about GPIO pin assignments and drive bays in the E250 and
v240.  Consolidate common code for v210/v240 and E250.
Modify the GPIO pin names to include a type (currently LED or INDICATOR)
which we can then handle in the driver.
