Subject: video: Assume video to be active if SPL is passing video hand-off
X-Git-Url: http://git.dujemihanovic.xyz/html/static/git-favicon.png?a=commitdiff_plain;h=4ac7ffb60ee9a342337dce6e4fda3cbac827c398;p=u-boot.git

video: Assume video to be active if SPL is passing video hand-off

If SPL is passing video handoff structure to U-boot then it is safe to
assume that SPL has already enabled video and that's why it is passing
video handoff structure to U-boot so that U-boot can preserve the
framebuffer.
