Various Makefiles: Add SPDX-License-Identifier tags

2015-11-10T14:19:52+00:00

After consulting with some of the SPDX team, the conclusion is that
Makefiles are worth adding SPDX-License-Identifier tags too, and most of
ours have one.  This adds tags to ones that lack them and converts a few
that had full (or in one case, very partial) license blobs into the
equivalent tag.

biosemu: Do not free vga_info->BIOSImage when it is 0xc0000

2015-04-30T00:51:49+00:00

For x86, vga_info->BIOSImage points to 0xc0000 which cannot be freed.

bios_emulator: Add some VESA interface debugging

2015-01-24T00:24:16+00:00

Allow the supported modes to be listed when in debug mode.

bios_emulator: Don't display error when emulator terminates

2015-01-24T00:24:15+00:00

As it turns out this is a normal condition, so suppress the error.

bios_emulator: Fix an #ifdef typo in the header file

2015-01-24T00:24:15+00:00

This stops the debug mode from working properly.

bios_emulator: Correct ordering of includes

2014-12-13T22:08:04+00:00

We should include common.h before other includes. This actually causes
a build error on chromebook_link.

bios_emulator: Always print errors when opcode decode fails

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

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.

bios_emulator: Add an option to enable debugging

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

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.

bios_emulator: Allow a custom interrupt handler to be installed

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

Sometime we want to provide an interrupt handler for the ROM, Add a
function to allow this.

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.
