Stefan Reinauer 57879c9bd1 Make the device tree available in the rom stage
We thought about two ways to do this change. The way we decided to try
was to
1. drop all ops from devices in romstage
2. constify all devices in romstage (make them read-only) so we can
   compile static.c into romstage
3. the device tree "devices" can be used to read configuration from
   the device tree (and nothing else, really)
4. the device tree devices are accessed through struct device * in
   romstage only. device_t stays the typedef to int in romstage
5. Use the same static.c file in ramstage and romstage

We declare structs as follows:
ROMSTAGE_CONST struct bus dev_root_links[];
ROMSTAGE_CONST is const in romstage and empty in ramstage; This
forces all of the device tree into the text area.

So a struct looks like this:
static ROMSTAGE_CONST struct device _dev21 = {
 #ifndef __PRE_RAM__
        .ops = 0,
 #endif
        .bus = &_dev7_links[0],
        .path = {.type=DEVICE_PATH_PCI,{.pci={ .devfn = PCI_DEVFN(0x1c,3)}}},
        .enabled = 0,
        .on_mainboard = 1,
        .subsystem_vendor = 0x1ae0,
        .subsystem_device = 0xc000,
        .link_list = NULL,
        .sibling = &_dev22,
 #ifndef __PRE_RAM__
        .chip_ops = &southbridge_intel_bd82x6x_ops,
 #endif
        .chip_info = &southbridge_intel_bd82x6x_info_10,
        .next=&_dev22
};

Stefan Reinauer 77adc5e03c Don't unconditionally add support for cardbus and pci-x devices
It's still on by default.

Patrick Georgi 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.

Myles Watson e3df121e4f Enable PCI_OPTION_ROM_REALMODE when GEODE_VSA is selected.
Using YABEL isn't supported for the VSA, so don't allow a choice.

Stefan Reinauer 859e94a304 it was reason for workaround rules already, and it's somewhat ugly:
util/x86emu is the only part of coreboot that is linked into coreboot
itself that lives in util/.
It's not a utility and it does not really belong where it lives.

---> svn mv util/x86emu src/devices/oprom

plus necessary Makefile changes to get it building again
