Stefan Reinauer 4172efc17f biosemu (non-yabel) cleanup
* Drop pcbios folder that only exists for a single function
* include int1a handler in biosemu.c
* Wipe a lot of dead code, and set up F segment correctly
* include return value check from yabel.

On the long run we should teach yabel to be able to run with a reduced feature
set, ie. no emulation of (almost) all system hardware. Then we could drop the
non-yabel x86emu.
But for now this patch cleans up the non-yabel biosemu.c to a state where it's
not all that ugly anymore..

Mark Marshall d08e69dd5e Use more care when implementing the PCI BIOS functions.
The READ_CONF and WRITE_CONF functions would both do the wrong thing
if the passed in BDF was not found.  We should return and error to the
caller, but not stop running the option ROM.

I slightly reworked the patch:

The 'CHECK' function seemed to be both wrong code and the wrong
number. 

In fact the CHECK function was given the function number of
the "Microsoft Real-Time Compression Interface". Since this is definitely wrong 
I removed the code.

Dropped some unneeded scopes, too, to make the code easier to read.

Stefan Reinauer 7110d40fbf x86emu: Add support for the following opcodes:
* SMSW
* INVD/WBINVD
* RDMSR/WRMSR
* CPUID

The implementation is kept very simple (mostly dummies) but it should get
us successfully through the Poulsbo VGA OPROM code in order to determine
further requirements.

Also, fix up a lot of warnings (mostly about missing prototypes for 
functions that should be static anyways)

This version adds a break in smsw that was missing in the patch that was sent
to the list.

Uwe Hermann 312673ca72 Improve coreboot build output and eliminate some warnings:
- Add static and const where possible.

 - Turn some #warning entries into TODO comments.

 - Add missing prototypes.

 - Remove unused variables.

 - Fix printf arguments or cast them as needed.

 - Make sconfig output look better. Drop useless "PARSED THE TREE" output.

 - Print "(this may take a while)" while building romcc. Add missing "\n".

Maciej Pijanka ea92185755 Add few missing prototypes, and remove few unused (thus lonelly) variables.
TODO
 - x86emu need (imo) some common header with prototypes at least
 - clog2, ulzma, hardwaremain prototypes added by this patch probably should 
   be moved to some header too.
 - in src/devices/device_util.c prototype is before function because seems, 
   it is used only within same file, if not it should be moved to debug
   section of prototypes in include/device/device.h

Stefan Reinauer 074356ec81 Option ROM init x86/x86emu update
- use default display in int 15 5f35
- move REALMODE_BASE to 0x600, 0x500 can be BDA
- add regparm for assembler functions
- use memset instead of own implementation
- YABEL: copy back the IVT, BDA and VBIOS. Some Xorg drivers require this.
- YABEL: use hardware timer instead of emulated timer, because the emulated
  timer's base is never initialized (leading to division by zero if the 
  timer is really used)

Uwe Hermann fe2664a5f2 Improve build output.
The Makefile prints need to be @printf -- not $(Q)printf -- as they should

 (1) be printed always (with 'make' _and_ with 'make V=1'),

 (2) but the printf command itself should not be printed, hence the '@'.

Uwe Hermann 5ec2c2b998 Various Kconfig and Makefile.inc fixes and cosmetics.
- Whitespace fixes, remove trailing whitespace, use TABs for identation
   (except in Kconfig "help" lines, which start with one TAB and two spaces
   as per Linux kernel style)

 - Kconfig: Standardize on 'bool' (not 'boolean').

 - s/lar/cbfs/ in one Kconfig help string.

 - Reword various Kconfig menu entries for a more usable and consistent menu.

 - Fix incorrect comment of NO_RUN in devices/Kconfig.

 - superio/serverengines/Kconfig: Incorrect config name.

 - superio/Makefile.inc: s/serverengine/serverengines/.

 - superio/intel/Kconfig: s/SUPERIO_FINTEK_I3100/SUPERIO_INTEL_I3100/.

 - mainboard/via/vt8454c/Kconfig: Fix copy-paste error in help string.

 - mainboard/via/epia-n/Kconfig: Fix "bool" menu text.

 - console/Kconfig: Don't mention defaults in the menu string, kconfig
   already displays them anyway.

 - Kill "Drivers" menu for now, it only confuses users as long as it's emtpy.

Stefan Reinauer 38cd29ebd7 Don't pull in x86emu from a foreign directory anymore. This
produced numerous problems in the past, including the fact that
x86emu doesn't work in v3 anymore even though it lives in the v3
repository.

Since this is a cross-repository move, keeping the history in the v2 tree 
would make life hard for everone. So check the v3 repository for x86emu history
since the merger. The his commit is based on an svn export of r1175 of the
coreboot-v3 repository.
