| * bios_emulator: Always print errors when opcode decode failsSimon Glass2014-11-25-18/+22
| | | | | | | | | | | | | | | | | | This is a rare event and should not happen. When it does it is confusing to work out why. At least we should print a message. Adjust the emulator to always print decode errors to the console. Signed-off-by: Simon Glass <sjg@chromium.org>
| * bios_emulator: Add an option to enable debuggingSimon Glass2014-11-25-54/+90
| | | | | | | | | | | | | | | | | | | | At present there are DEBUG options spread around the place. If you enable one and not another you can end up with an emulator that does not work, since each file can have a different view of what the registers look like. To fix this, create a global CONFIG_X86EMU_DEBUG option that keeps everything consistent. Signed-off-by: Simon Glass <sjg@chromium.org>
| * bios_emulator: Allow a custom interrupt handler to be installedSimon Glass2014-11-25-0/+6
| | | | | | | | | | | | | | Sometime we want to provide an interrupt handler for the ROM, Add a function to allow this. Signed-off-by: Simon Glass <sjg@chromium.org>
| * bios_emulator: Add vesa support and allow ROMs to be passed in as dataSimon Glass2014-11-25-58/+152
| | | | | | | | | | | | | | | | | | As well as locating the ROM on the PCI bus, allow the ROM to be supplied to the emulator. Split the init up a little so that callers can supply their own interrupt routines. Also allow a vesa mode to be provided, to be selected once the BIOS run is complete.

| * bios_emulator: Allow x86 to use the emulatorSimon Glass2014-11-25-23/+23
| | | | | | | | | | | | | | | | | | | | | | There is an implicit assumption that x86 machines want to use raw I/O in the BIOS emulator, but this should be selectable. Add an CONFIG_X86EMU_RAW_IO option to control it instead. Also fix a few bugs which cause warnings on x86 and adjust the Makefile to remove the assumption that only PowerPC uses the emulator.

| * x86: Add initial video device init for Intel GMASimon Glass2014-11-25-1/+969
| | | | | | | | | | | | | | | | | | 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>
| * x86: Allow an option ROM to be built into U-BootSimon Glass2014-11-25-0/+3
| | | | | | | | | | | | | | | | Some x86 machines require a binary blob containing 16-bit initialisation code for their video hardware. Allow this to be built into the x86 ROM so that it is accessible during boot. Signed-off-by: Simon Glass <sjg@chromium.org>
| * x86: video: Add video driver for bare x86 boardsSimon Glass2014-11-25-0/+38
| | | | | | | | | | | | | | | | Add a very simple driver which uses vesa to discover the video mode and then provides a frame buffer for use by U-Boot. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>
| * pci: Add general support for execution of video ROMsSimon Glass2014-11-25-2/+353
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some platforms don't have native code for dealing with their video hardware. In some cases they use a binary blob to set it up and perform required actions like setting the video mode. This approach is a hangover from the old PC days where a ROM was provided and executed during startup. Even now, these ROMs are supplied as a way to set up video. It avoids the code for every video chip needing to be provided in the boot loader. But it makes the video much less flexible - e.g. it is not possible to do anything else while the video init is happening (including waiting hundreds of milliseconds for display panels to start up). In any case, to deal with this sad state of affairs, provide an API for execution of x86 video ROMs, either natively or through emulation. Signed-off-by: Simon Glass <sjg@chromium.org>
| * x86: Add support for running option ROMs nativelySimon Glass2014-11-25-0/+946
| | | | | | | | | | | | | | | | On x86 machines we can use an emulator to run option ROMS as with other architectures. But with some additional effort (mostly due to the 16-bit nature of option ROMs) we can run them natively. Add support for this. Signed-off-by: Simon Glass <sjg@chromium.org>
| * Add support for Vesa BIOS extensionsSimon Glass2014-11-25-0/+103
| | | | | | | | | | | | | | For option ROMs we can use these extensions to request a particular video mode. Add a header file which defines the binary interface. Signed-off-by: Simon Glass <sjg@chromium.org>

| * x86: Add GDT descriptors for option ROMsSimon Glass2014-11-25-22/+18
| | | | | | | | | | | | | | Option ROMs require a few additional descriptors. Add these, and remove the enum since we now have to access several descriptors from assembler. Signed-off-by: Simon Glass <sjg@chromium.org>
| * Introduce a header file for the BIOS emulatorSimon Glass2014-11-25-52/+46
| | | | | | | | | | | | | | We should have a public header so that users can avoid defining functions themselves. Signed-off-by: Simon Glass <sjg@chromium.org>
| * x86: Add a definition of asmlinkageSimon Glass2014-11-25-0/+3

| * x86: Call cpu_init_interrupts() from interrupt_init()Bin Meng2014-11-25-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently cpu_init_interrupts() is called from cpu_init_r() to setup the interrupt and exception of the cpu core, but at that time the i8259 has not been initialized to mask all the irqs and remap the master i8259 interrupt vector base, so the whole system is at risk of being interrupted, and if interrupted, wrong interrupt/exception message is shown.
