From 4b42cc4b31f682214ab473838f0de0584f58cba8 Mon Sep 17 00:00:00 2001 From: Patrick Rudolph Date: Mon, 29 May 2017 19:25:10 +0200 Subject: SeaVGABios/cbvga: Advertise correct pixel format Accumulate the pixel format's bits instead relying on coreboot's bits_per_pixel, which says nothing about the active pixel format. Allows VBE to correctly advertise XRGB8 and BGRX8 framebuffer formats, commonly used by coreboot. Fixes at least Windows Bootloader and gfxboot.
