From: Alexandre Courbot Date: Wed, 14 Dec 2016 08:02:45 +0000 (+0900) Subject: drm/nouveau/secboot: abstract LS firmware loading functions X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9d896f3e41a6093a843ce668c97159367c1e4573;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/nouveau/secboot: abstract LS firmware loading functions 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.
