2014-05-17build: allow romcc to be wrappedPatrick Georgi
Allow ccache and scan-build to wrap romcc. This works a bit different from the other compilers because we only define it later.

2014-05-15rambi: Add ACPI table support for I2C devicesDuncan Laurie
In order to support probing I2C devices when the controller is in ACPI mode the mainboard needs to decalre them in the proper scope with the address/interrupt information. The touchpad devices are ATML0000/ELAN0000 and the touchscreen is ATML0001 so they can be distinguished in userland scripts based on ID. There is also a special "ISTP" node that indicates whether the devices is a touchpad (=1) or touchscreen (=0) in case this is useful to drivers. These names may not be final but they are a starting point and can be easily changed. Atmel devices also have a bootloader mode which needs to be declared as a separate device. Unfortunately it does not work as expected to have multiple I2cSerialBus() resources declared in a single device and have it select properly, even with the use of StartDependentFn(), so bootloader devices are declared separately. The original devices are left in \_SB scope and are only enabled if the I2C controllers are in PCI mode. The new devices are only enabled if the I2C controllers are in ACPI mode. BUG=chrome-os-partner:24380 BRANCH=baytrail TEST=manual 1) Ensure there is no change in functionality by default and that the devices are still probed by chromeos_laptop in the kernel. 2) Enable lpss_acpi_mode=1 in devicetree.cb and kernel changes to add _HID entries for devices in appropriate drivers. Ensure that the devices are probed successfully. Further changes are needed to the chromeos-touch-firmware scripts to load config and update firmware based on the new ACPI _HID entries. 3) Put touchpad in bootloader mode (by flashing bad firmware) and ensure that it is detected at address 0x25 and the firmware is able to be updated.

2014-05-13baytrail: reboot with EC in S0 with no MRC cache and EC in RWAaron Durbin
This improves boot time in 2 ways for a firmware upgrade: 1. Normally MRC would detect the S0 state without an MRC cache even though it's told to the S5 path. When it observes this state a cold reset occurs. The cold reset stays in S5 for at least 4 seconds which is time observed by the end user. 2. As the EC was running RW code before the reset after firmware upgrade it will still be running the older RW code. Vboot will then reboot the EC and the whole system to put the EC into RO mode so it can handle the RW update. The issues are mitigated by detecting the system is in S0 with no MRC cache and the EC isn't in RO mode. Therefore we can do the reboot without waiting the 4 secs and the EC is running RO so the 2nd reboot is not necessary. BUG=chrome-os-partner:24133 BRANCH=rambi,squawks TEST=Booted.

2014-05-13baytrail: dptf: Add disable trip point methodsDuncan Laurie
Added a method in each temp sensor to disable the aux trip points and then a wrapper function to call this method for each enabled temperature sensor. The event handler function is changed to not use a switch statement so it does not need to be serialized. This was causing issues with nested locking between the global lock and the EC PATM mutex. Some unused code in temp sensors that was added earlier is removed and instead a critical threshold is specified in _CRT. The top level DPTF device _OSC method is expanded to check for the passive policy UUID and initialize thermal devices. This is done for both enable and disable steps to ensure that the EC thermal thresholds are reset in both cases. Additionally the priority based _TRT is specified with TRTR=1. BUG=chrome-os-partner:17279 BRANCH=rambi TEST=build and boot on rambi, load esif_lf kernel drivers and start esif_uf application.

2014-05-10baytrail: Add support for LPSS and SCC devices in ACPI modeDuncan Laurie
This adds the option to put LPSS and SCC devices into ACPI mode by saving their BAR0 and BAR1 base addresses in a new device NVS structure that is placed at offset 0x1000 within the global NVS table. The Chrome NVS strcture is padded out to 0xf00 bytes so there is a clean offset to work with as it will need to be used by depthcharge to know what addresses devices live at. A few ACPI Mode IRQs are fixed up, DMA1 and DMA2 are swapped and the EMMC 4.5 IRQ is changed to 44. New ACPI code is provided to instantiate the LPSS and SCC devices with the magic HID values from Intel so the kernel drivers can locate and use them. The default is still for devices to be in PCI mode so this does not have any real effect without it being enabled in the mainboard devicetree. Note: this needs the updated IASL compiler which is in the CQ now because it uses the FixedDMA() ACPI operator. BUG=chrome-os-partner:23505,chrome-os-partner:24380 CQ-DEPEND=CL:179459,CL:179364 BRANCH=none TEST=manual tests on rambi device: 1) build and boot with devices still in PCI mode and ensure that nothing is changed 2) enable lpss_acpi_mode and see I2C devices detected by the kernel in ACPI mode. Note that by itself this breaks trackpad probing so that will need to be implemented before it is enabled. 3) enable scc_acpi_mode and see EMMC and SDCard devices detected by the kernel in ACPI mode. Note that this breaks depthcharge use of the EMMC because it is not longer discoverable as a PCI device.
