2015-07-27Kill unneeded #include <linux/kconfig.h>Masahiro Yamada
Because the top-level Makefile forces all the source files to include include/linux/kconfig.h (see the UBOOTINCLUDE define), these includes are redundant. By the way, there are exceptions for the statement above; host programs. In fact, host tools in U-Boot depend on a particular board configuration, although I think they should not. So, some files still include <linux/config.h> to work around build errors on host tools.

2015-04-16x86: Add a x86_ prefix to the x86-specific PCI functionsSimon Glass
These functions currently use a generic name, but they are for x86 only. This may introduce confusion and prevents U-Boot from using these names more widely. In fact it should be possible to remove these at some point and use generic functions, but for now, rename them.

2015-02-05x86: video: Allow video ROM execution to fall back to the other methodSimon Glass
If the BIOS emulator is not available, allow use of native execution if available, and vice versa. This can be controlled by the caller. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2015-01-13x86: ivybridge: Set up an MTRR for the video frame bufferSimon Glass
Set the frame buffer to write-combining. This makes it faster, although for scrolling write-through is even faster for U-Boot. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-01-13x86: ivybridge: Only run the Video BIOS when video is enabledSimon Glass
This takes about about 700ms on link when running natively and 900ms when running using the emulator. It is a waste of time if video is not enabled, so don't bother running the video BIOS in that case. We could add a command to run the video BIOS later when needed, but this is not considered at present. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2014-11-25x86: Add initial video device init for Intel GMASimon Glass
Intel's Graphics Media Accelerator (GMA) is a generic name for a wide range of video devices. Add code to set up the hardware on ivybridge. Part of the init happens in native code, part of it happens in a 16-bit option ROM for those nostalgic for the 1970s. Signed-off-by: Simon Glass <sjg@chromium.org>
