[Nouveau] [PATCH v4 14/33] secboot: abstract LS firmware loading functions
Alexandre Courbot
acourbot at nvidia.com
Mon Nov 21 08:29:11 UTC 2016
The WPR and LSB headers, used to generate the LS blob, may have a
different layout and sizes depending on the driver version they come
from. Abstract them and confine their use to driver-specific code.
