From 7981394e550094bbbb2eb5e62065fa14c2ca77b0 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 13 Nov 2016 14:22:06 -0700 Subject: [PATCH] video: Use cache-alignment in video_sync() Sometimes the frame buffer is not a multiple of the cache line size. Adjust the cache-flushing code to avoid cache warnings/errors in this case.
