From 644e61448cb02c6252b3f9131bff82e92a0f2aea Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Fri, 10 Mar 2023 12:47:13 -0800 Subject: efi: Support a 64-bit frame buffer address The current vesa structure only provides a 32-bit value for the frame buffer. Many modern machines use an address outside the range. It is still useful to have this common struct, but add a separate frame-buffer address as well. Add a comment for vesa_setup_video_priv() while we are here.
