Subject: [PATCH] overlays: Add a sample hat_map
|
|
|
|
The HAT map is way of associating named overlays with HATs whose
|
|
EEPROMs were programmed with the contents of the overlay.
|
|
Unfortunately, change in the DT and kernel drivers has meant that some
|
|
of these embedded overlays no longer function, or even don't apply.
|
|
|
|
The HAT map is a mapping from HAT UUIDs to overlay names. If a HAT with
|
|
a listed UUID is detected, the embedded overlay is ignored and the
|
|
overlay named in the mapping is loaded in its place.
