2013-07-10ec: Add romstage function for checking and rebooting ECDuncan Laurie
Now that we are executing VbInit() in coreboot we can end up in a situation where the recovery reason is consumed during VbInit (end of romstage) and then the EC is rebooted to RO during ramstage EC init, thereby losing the recovery reason. Two possiblities are to remove the EC check+reboot from ramstage and let it happen in depthcharge. This however means that the system has to boot all the way into depthcharge and then reboot the EC and the system again. Instead if we do a check in romstage before VbInit() is called then we can reboot the EC into RO early and avoid booting all the way to depthcharge first. This change adds a ramstage version the EC init function and calls it from the shared romstage code immediately after the PCH decode windows are setup.

Prior doing so, two macros should be defined to identify the used i/o ports: * EC_SC_IO I/o address of the EC_SC register * EC_DATA_IO I/o address of the EC_DATA register Change-Id: I8c6706075fb4980329c228e5b830d5f4e9b188dd Signed-off-by: Nico Huber <nico.huber@secunet.com> Reviewed-on: http://review.coreboot.org/3285 Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org> Tested-by: build bot (Jenkins)

Here's the great news: From now on you don't have to worry about hitting the right io.h include anymore. Just forget about romcc_io.h and use io.h instead. This cleanup has a number of advantages, like you don't have to guard device/ includes for SMM and pre RAM anymore. This allows to get rid of a number of ifdefs and will generally make the code more readable and understandable. Potentially in the future some of the code in the io.h __PRE_RAM__ path should move to device.h or other device/ includes instead, but that's another incremental change.

2012-11-27Get rid of drivers classPatrick Georgi
The use of ramstage.a required the build system to handle some object files in a special way, which were put in the drivers class. These object files didn't provide any symbols that were used directly (but only via linker magic), and so the linker never considered them for inclusion. With ramstage.a gone, we can drop this special class, too.

2012-08-04Make the device tree available in the rom stageStefan Reinauer
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 }; Change-Id: I722454d8d3c40baf7df989f5a6891f6ba7db5727 Signed-off-by: Ronald G.

2011-10-20T60: Add support for Ultrabay Legacy I/O devices (40Y8122)Sven Schnelle
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.

2011-08-19Lenovo H8: Always clear audio muteSven Schnelle
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.

2011-06-23T60: undock on external power lossSven Schnelle
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.
