qemu: cirrus native video init Recent commit proposal by Ron Minnich proposes to move to native gfx init for qemu. Unfortunately we didn't have native init for default qemu video (cirrus) Here is one extracted from GRUB one which I wrote couple of years ago.

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.

edid: Make framebuffer row alignment configurable Our EDID code had always been aligning the framebuffer's bytes_per_line (and x_resolution dependent on that) to 64. It turns out that this is a controller-dependent parameter that seems to only really be necessary for Intel chipsets, and commit 6911219cc (edid: Add helper function to calculate bits-per-pixel dependent values) probably actually broke this for some other controllers by applying the alignment too widely. This patch makes it explicitly configurable and depends the default on ARCH_X86 (which seems to be the simplest and least intrusive way to make it fit most cases for now... boards where this doesn't apply can still override it manually by calling edid_set_framebuffer_bits_per_pixel() again).
