557ecf2d31 Simplify VGA card discovery
We were handling vga, vga_first, vga_last, vga_onboard just to determine
an onboard chip and the first plugin card.
We were also traversing the devices manually instead of using the utility
functions we have, for the chance that there are non-VGA cards we need to
cope with (but why would they require VGA-style handling?)

5869fa2e63 Allow shutting down internal graphics if plugin graphics are preferred
VGA is this part-legacy thing that can cause trouble...

For this, introduce device_t->disable(dev) method, in which a driver
can take care to deregister the device if necessary.

c4b2a1b6de Allow YABEL to fake write accesses to config space
A new Kconfig option tells YABEL to succeed on write accesses
on other devices' config space without performing the actual
write.
This is enough for some basic bus modification done by some
Option ROMs.

0fa50a1990 MPTAPLE: generate from devicetree.cb
This patch adds support for autogenerating the MPTABLE from
devicetree.cb. This is done by a write_smp_table() declared
weak in mpspec.c. If the mainboard doesn't provide it's own
function, this generic implementation is called.

Syntax in devicetree.cb:

ioapic_irq <APICID> <INTA|INTB|INTC|INTD> <INTPIN>

The ioapic_irq directive can be used in pci and pci_domain
devices. If there's no directive, the autogen code traverses
the tree back to the pci_domain and stops at the first device
which such a directive, and use that information to generate the
entry according to PCI IRQ routing rules.

97de28da8a PCI Type2 config must die
PCI Type 2 config was a strange and never-used config mechanism.
It is unlikely that in the 13 years of coreboot's existence that
type 2 was ever used; it just made life complicated for everyone.
It lived long enough in coreboot to be replaced by mmioconf.
Prior to making the device tree visible in romstage we want to
get rid of type2.

Delete two files we don't need any more (yay!).
Replace two functions with one: pci_config_default, which returns
a pointer to the default config method. At some future time this
may change to mmio but for now it is old type1 style.

8049fc91de Allow device ID arrays in the PCI driver structure
Many PCI devices share the very same driver despite having different
PCI device IDs, which causes a lot of copy and paste of driver
definitions.

This change introduces a way to specify the array of acceptable
device IDs in a single driver entry. As an example the Intel
{Sandy|Ivy} Bridge SATA driver is being modified to use a single
driver structure for all different SATA controller flavors, a few
more Ivy Bridge IDs are being added as well.

BUG=none
TEST=manual
  . modified coreboot brought up an Ivy Bridge platform all the
    way to Linux login screen.

971804ed68 x86, oprom: ensure DF is always cleared
The Option ROM might mess with the EFLAGS register and break assumptions
the C part of coreboot implicitly has, e.g. the state of the direction
flag.

Prevent Option ROMs from confusing coreboot by restoring the old EFLAGS
value after the Option ROMs has finished and always clear the direction
flag before calling the C part of the interrupt handler.

74a0efe09a [ChromeOS] Don't initialize VGA Option ROM in normal mode
ChromeOS features two different modes: normal mode and developer mode

However, in normal mode we want to boot blazingly fast. Therefore we
don't run (VGA) option ROMs, unless we have to print something on the
screen before the kernel is loaded.

b4aaaa7632 Prepare the BIOS data areas before device init.
Since we do not run option roms in normal mode nothing was
initializing the BDA/EBDA and yet Linux depends very much
on it having sane values here.  For the most part the kernel
tries to work around this not being initialized, but every
once in awhile (1/300 boots or so) it would end up reading
something that looked sane from BDA but was not and then
it would panic.

In this change the EBDA is unconditionally setup before devices
are initialized.  I'm not set on the location in dev_initialize()
but there does not seem to be another place to hook it in so
that it runs just once for ALL platforms regardless of whether
they use option roms or not. (possibly hardwaremain?)

The EBDA setup code has been moved into its own location in
arch/x86/lib/ebda.c so it can be compiled in even if the option
rom code is not.

The low memory size is still set to 1MB which is enough to make
linux happy without having to hook into each mainboard to get a
more appropriate value.  The setup_ebda() function takes inputs
so it could be changed for a mainboard if needed.

OLD/BROKEN would read garbage.  Examples from different boots:
ebda_addr=0x75e80 lowmem=0x1553400
ebda_addr=0x5e080 lowmem=0x3e51400
ebda_addr=0x7aa80 lowmem=0x2f8a800

NEW/FIXED now reads consistent values:
ebda_addr=0xf6000 lowmem=0x100000

8660a1aa56 Fix multipleVGA cards resource conflict on Windows
If multiple VGA-compatible legacy graphic cards decode the IO range
3B0-3BB, 3C0-3DF and MEM range A00000-BFFFF.
Windows 7 complain a resource conflict, so only one VGA card can
works at the same time.

There is a discussion in coreboot mail list before,
please reference thread: "how to prevent legacy resource conflictwith   multipleVGA cards"
http://www.coreboot.org/pipermail/coreboot/2010-October/061508.html

Linux using VGA Arbiter module(vgaarb) to resolve this resource conflict,
Please see the following linux dmesg log, more information can be found in
Linux source dir Documentation/vgaarbiter.txt.
But it seems that windows don't dealwith this conflict.
~# dmesg | grep -i vgaarb
[    0.774076] vgaarb: device added: PCI:0000:00:01.0,decodes=io+mem,owns=io+mem
[    0.776065] vgaarb: device added: PCI:0000:01:00.0,decodes=io+mem,owns=none,l
[    0.780051] vgaarb: loaded
[    0.784049] vgaarb: bridge control possible 0000:01:00.0
[    0.788050] vgaarb: bridge control possible 0000:00:01.0

For the second legacy graphic device, coreboot already disabled the
IO and MEM decode in function set_vga_bridge_bits().
But it will be enabled again in function pci_set_resource(),
if the second legacy vga-compatible graphic device take any IO/MEM resources.

Following log printed by enable_resources() shows the problem:
...snip...
PCI: 00:00.0 cmd <- 06
PCI: 00:01.0 subsystem <- 1022/1410
PCI: 00:01.0 cmd <- 07                <== The first graphic device
PCI: 00:01.1 subsystem <- 1022/1410
PCI: 00:01.1 cmd <- 02
PCI: 00:02.0 bridge ctrl <- 0003
PCI: 00:02.0 cmd <- 07
...snip...
PCI: 01:00.0 cmd <- 03                <== The second graphic device
PCI: 01:00.1 cmd <- 02
PCI: 02:00.0 cmd <- 02
PCI: 03:00.0 cmd <- 03
done.
...snip...


The IO & MEM decoding on the second vga graphic device should be disabled.
Please reference PCI spec. section 3.10 in detail.
set_vga_bridge_bits() would do this work for us, it did the right thing,
but was put to the wrong place, the setting would be overwritten by
assign_resources() later.

In order to make sure the set_vga_bridge_bits() setting not be
overwritten by others, moving the call of set_vga_bridge_bits()
to the end of dev_configure(), instead of at the beginning.

This patch resolved the dual graphic cards resource conflict in windows7,
multiple vga-compatible graphic cards can work together in windows7.

c0a6c6b3b9 Add OPROM mapping support to coreboot
This allows to add a PCI ID mapping function for option roms so that the same

use the same option rom for a number of PCI devices with differend IDs.

appropriate):

/* some vga option roms are used for several chipsets but they only have one
 * PCI ID in their header. If we encounter such an option rom, we need to do
 * the mapping ourselfes
 */

u32 map_oprom_vendev(u32 vendev)
{
    u32 new_vendev=vendev;

    switch(vendev) {
    case 0xa0118086:
        new_vendev=0xa0018086;
        break;
    }

b6b8871dd3 Fix native x86 option rom initialization
- Intel option roms want an initialized i8259 or they will
  throw an exception 6. This should be done in the southbridge
  code, but that is executed much later than the VGA init, so
  initialize the i8259 in src/devices/oprom/x86.c.
  In the long run this will allow getting rid of some of the
  ugly hacks in some AMD boards' romstage.c
- Don't overwrite the mode when copying mode info information back
  from 0x600.

9144304771 Improve compatibility of YABEL with real-world VGABIOSes
Some of them do weird things to the option rom region (mapping
registers there or so) which failed as we handled these memory
region in emulation. As they were copied back to real memory
after the emulation was done, we can just as well use real
memory directly for these regions.

This affects IVT, BDA, and option ROM space.

abc0c85516 Printing coreboot debug messages on VGA console is pretty much useless, since
initializing VGA happens pretty much as the last thing before starting the
payload. Hence, drop VGA console support, as we did in coreboot v3.

- Drop VGA and BTEXT console support. 
  Console is meant to be debugging only, and by the time graphics comes up
  99% of the risky stuff has already happened. Note: This patch does not remove
  hardware init but only the actual output functionality. 

  The ragexl driver needs some extra love, but that's for another day
- factor out die() and post()
- drop some leftover RAMBASE < 0x100000 checks.

The following functions are moved to devices/device_util.c:

 - ram_resource()

 - tolm_test()

 - find_pci_tolm()

There are only two tolm_test() / find_pci_tolm() which differ from the
defaults, one of them can easily be eliminated in a follow-up patch,
maybe even both, but for now keep it simple and only eliminate the majority.

8463dd9db0 Rename build system variables to be more intuitive, and
at the same time let the user specify sources instead
of object files:
- objs becomes ramstage-srcs
- initobjs becomes romstage-srcs
- driver becomes driver-srcs
- smmobj becomes smm-srcs

The user servicable parts are named accordingly:
ramstage-y, romstage-y, driver-y, smm-y

Also, the object file names are properly renamed now, using
.ramstage.o, .romstage.o, .driver.o, .smm.o suffixes consistently.

Remove stubbed out via/epia-m700 dsdt/ssdt files - they didn't
easily fit in the build system and aren't useful anyway.
