This does not work on some 64-bit machines since only a 32-bit address for the framebuffer is supported in the VESA structure.
This series corrects this and makes a few other minor, video-related improvements.
Changes in v3: - Use Returns instead of @return - Show the CPU vendor name also - Add a comment about the value - Add a comment about the fallback
Changes in v2: - Obtain copy framebuffer size from EFI instead of using a fixed value - Dropping debugging printf() - Use new bootph-xxx tag - Add new patch to show the size of the copy framebuffer with bdinfo
Simon Glass (13): efi: video: Move payload code into a function efi: video: Return mode info for app also efi: Support a 64-bit frame buffer address x86: Add a few more items to bdinfo efi: Use a fixed value for the timer clock efi: Support copy framebuffer video: Allow a copy framebuffer with pre-allocated fb bbinfo: Show the size of the copy framebuffer efi: Adjust script to show pre-relocation output on terminal video: Remove duplicate cursor-positioning function video: Clear the vidconsole rather than the video efi: Add dhrystone, dcache and scroll lines to app video: Add a note about the broken implementation
