From 92106b166671a315a2b1e8f5cc467f2fa0823301 Mon Sep 17 00:00:00 2001 From: Patrick Rudolph Date: Wed, 19 Feb 2020 12:54:06 +0100 Subject: drivers: Replace multiple fill_lb_framebuffer with single instance Currently it's not possible to add multiple graphics drivers into one coreboot image. This patch series will fix this issue by providing a single API that multiple graphics drivers can use. This is required for platforms that have two graphic cards, but different graphic drivers, like Intel+Aspeed on server platforms or Intel+Nvidia on consumer notebooks. The goal is to remove duplicated fill_fb_framebuffer(), the advertisment of multiple independent framebuffers in coreboot tables, and better runtime/build time graphic configuration options. Replace all duplications of fill_fb_framebuffer and provide a single one in edid_fill_fb.c. Should not change the current behaviour as still only one graphic driver can be active at time.
