* dm: Use uclass_first_device_err() where it is usefulSimon Glass2016-03-141-3/+3
| | | | | | Use this new function in places where it simplifies the code. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: ivybridge: Use syscon for the GMA deviceSimon Glass2016-01-241-3/+5
| | | | | | | | | Until we have a proper video uclass we can use syscon to handle the GMA device, and avoid the special device tree and PCI searching. Update the code to work this way. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* x86: ivybridge: Sort out the calls to bridge_silicon_revision()Simon Glass2016-01-241-16/+17
| | | | | | | | This function is called all over the place. Convert it use the driver model PCI API, and rationalise the calls. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* x86: ivybridge: Move lpc_enable() into gma.cSimon Glass2016-01-241-0/+4
| | | | | | | | This graphics init code is best placed in the gma init code. Move the code and drop the function. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* x86: ivybridge: Move graphics init much laterSimon Glass2016-01-241-0/+73
| | | | | | | | We don't need to init the graphics controller so early. Move it alongside the other graphics setup, just before we run the ROM. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* dm: pci: video: Convert video and pci_rom to use DM PCI APISimon Glass2016-01-121-2/+2
| | | | | | | | | | Adjust these files to use the driver-model PCI API instead of the legacy functions. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Tested-by: Bin Meng <bmeng.cn@gmail.com>
* dm: x86: ivybridge: Convert graphics init to use DM PCI APISimon Glass2016-01-121-8/+7
| | | | | | | | | Use the driver-model PCI functions here where possible. For now we have to search for the device with pci_bus_find_bdf() but at some point we can put this in a proper driver and avoid this. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* Kill unneeded #include <linux/kconfig.h>Masahiro Yamada2015-07-271-1/+0
| | | | | | | | | | | | | | | | 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.

* x86: Add a x86_ prefix to the x86-specific PCI functionsSimon Glass2015-04-161-2/+2
| | | | | | | | | | | | 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.

* x86: video: Allow video ROM execution to fall back to the other methodSimon Glass2015-02-051-1/+2
| | | | | | | | 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>
* x86: ivybridge: Set up an MTRR for the video frame bufferSimon Glass2015-01-131-0/+7
| | | | | | | 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>
* x86: ivybridge: Only run the Video BIOS when video is enabledSimon Glass2015-01-131-1/+8
| | | | | | | | | | | | 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>
* x86: Add initial video device init for Intel GMASimon Glass2014-11-251-0/+756
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>
