From 6d8266b91d7c8338350f7f8b81c21d10c97aceb6 Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Sat, 20 May 2017 16:46:01 +0200 Subject: Kconfig: Add choice of framebuffer mode Rename `FRAMEBUFFER_KEEP_VESA_MODE` to `LINEAR_FRAMEBUFFER` and put it together with new `VGA_TEXT_FRAMEBUFFER` into a choice. There are two versions of `LINEAR_FRAMEBUFFER` that differ only in the prompt and help text (one for `HAVE_VBE_LINEAR_FRAMEBUFFER` and one for `HAVE_LINEAR_FRAMEBUFFER`). Due to `kconfig_lint` we have to model that with additional symbols.
