2016-04-07edid: Make framebuffer row alignment configurableJulius Werner
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).

2016-03-24edid: Add helper function to calculate bits-per-pixel dependent valuesJulius Werner
Coreboot and most payloads support three basic pixel widths for the framebuffer. It assumes 32 by default, but several chipsets need to override that value with whatever else they're supporting. Our struct edid contains multiple convenience values that are directly derived from this (and other properties), so changing the bits per pixel always requires recalculating all those dependents in the chipset code. This patch provides a small convenience wrapper that can be used to consistently update the whole struct edid with a new pixel width instead, so we no longer need to duplicate those calculations everywhere. BUG=None TEST=Booted Oak in all three pixel widths (which it conveniently all supports), confirmed that images looked good.

Commit "7dbf9c6 edid: Use edid_mode struct to reduce redundancy" moved some fields from "struct edid" to "struct edid_mode". Adapt the bochs and cirrus drivers to that change.

commit 9518b56 (intel/gma: Clarify code and use dedicated init for Google Peppy) changed "struct edid" and thereby broke the build. Adapt drivers/emulation/qemu/bochs.c to the changes to fix this. Build failure triggers with CONFIG_FRAMEBUFFER_KEEP_VESA_MODE=y.

2013-11-25bochs: add support for native graphicsRonald G. Minnich
Per our discussions with Gerd, qemu will now always do native graphics on coreboot. The VGA BIOS capability is not needed and will no longer be supported. Attempts to build without native graphics will result in an error. This code builds for both x86 emulation targets. I'm hitting an issue testing that is unrelated to coreboot; if someone can test, that would be helpful. Be sure to start qemu with -vga std. We also add a test for the PCI BAR being zero and return silently if it is. Change-Id: I66188f61e1bac7ad93c989cc10f3e0b55140e148 Signed-off-by: Ronald G.
