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: NSimon Glass <sjg@chromium.org>

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: NSimon Glass <sjg@chromium.org> Acked-by: NAnatolij Gustschin <agust@denx.de>

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: NSimon Glass <sjg@chromium.org>

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: NSimon Glass <sjg@chromium.org>

Rename interrupt_init() in arch/x86/lib/pcat_interrupts.c to i8259_init() and create a new interrupt_init() in arch/x86/cpu/interrupt.c to call i8259_init() followed by a call to cpu_init_interrupts().

Since cpu_init_interrupts() was moved out of cpu_init_r(), it is useless to keep cpu_init_r() for x86, thus remove it. Signed-off-by: NBin Meng <bmeng.cn@gmail.com> Acked-by: NSimon Glass <sjg@chromium.org> Tested-by: NSimon Glass <sjg@chromium.org>

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.
