dm: pci: Convert bios_emu to use the driver model PCI API

2016-01-24T04:07:19+00:00

At present this BIOS emulator uses a bus/device/function number. Change
it to use a device if CONFIG_DM_PCI is enabled.

dm: x86: pci: Adjust bios_run_on_x86() to use the DM PCI API

2016-01-12T17:19:09+00:00

This function should take a struct udevice rather than pci_dev_t. Update it.

bios_emulator: Add vesa support and allow ROMs to be passed in as data

2014-11-25T14:11:17+00:00

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.

pci: Add general support for execution of video ROMs

2014-11-25T14:11:14+00:00

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.

Introduce a header file for the BIOS emulator

2014-11-25T13:34:14+00:00

We should have a public header so that users can avoid defining functions
themselves.
