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
};

Those modules have basically the same Super I/O capabilities as
the Docking station. Unfortunately, the Super I/O in the module
shares the same I/O address as the Docking station, so we're not
allowed to connect the LPC Docking Bus if such a module is present.
To be able to detect this device and use it as early console for
coreboot, we have to initialize the GPIO Controller before, as
this device is detected via GPIO06.

The mute bit is set by ACPI before poweroff/going to suspend.
So clear it after resume, to have working volume control
even if the ACPI doesn't clear it on resume.
OSPM should control Audio mute with ec bit 0x30:6, so it is
safe to clear this bit even if the user has audio muted.

If power is unplugged/lost, we should undock the docking station.
The power loss can also be caused by the fact that the user removed
the thinkpad from the docking station without pressing the Undock button/hotkey
first. Without undocking it on this event, the thinkpad LPC switch will still
connect the Docking connector, which causes crashes when docking it again.

This option is PMH7 specific, and should be moved there,
so all Notebook utilizing a PMH7 have this option.
For Thinkpads without Touchpad (like the X60), simply
don't add 'touchpad' to cmos.layout.

Move the EC support code from the X60 mainboard to a generic
driver, as this EC is used in many thinkpads. Also move the
ACPI code to this directory for this reason.
This patch also adds a chip config, so that the initial setting
