2014-05-13baytrail: snapshot power state in romstageAaron Durbin
The memory reference code doesn't maintain some of the registers which contain valuable information in order to log correct reset and wake events in the eventlog. Therefore snapshot the registers which matter in this area so that they can be consumed by ramstage. BUG=chrome-os-partner:24907 BRANCH=rambi,squawks TEST=Did various resets/wakes with logging patch which consumes this structure. Eventlog can pick up reset events and power failures.

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.

2014-05-06Introduce stage-specific architecture for corebootFurquan Shaikh
Make all three coreboot stages (bootblock, romstage and ramstage) aware of the architecture specific to that stage i.e. we will have CONFIG_ARCH variables for each of the three stages. This allows us to have an SOC with any combination of architectures and thus every stage can be made to run on a completely different architecture independent of others. Thus, bootblock can have an x86 arch whereas romstage and ramstage can have arm32 and arm64 arch respectively. These stage specific CONFIG_ARCH_ variables enable us to select the proper set of toolchain and compiler flags for every stage. These options can be considered as either arch or modes eg: x86 running in different modes or ARM having different arch types (v4, v7, v8). We have got rid of the original CONFIG_ARCH option completely as every stage can have any architecture of its own. Thus, almost all the components of coreboot are identified as being part of one of the three stages (bootblock, romstage or ramstage). The components which cannot be classified as such e.g. smm, rmodules can have their own compiler toolset which is for now set to *_i386. Hence, all special classes are treated in a similar way and the compiler toolset is defined using create_class_compiler defined in Makefile. In order to meet these requirements, changes have been made to CC, LD, OBJCOPY and family to add CC_bootblock, CC_romstage, CC_ramstage and similarly others. Additionally, CC_x86_32 and CC_armv7 handle all the special classes. All the toolsets are defined using create_class_compiler. Few additional macros have been introduced to identify the class to be used at various points, e.g.: CC_$(class) derives the $(class) part from the name of the stage being compiled. We have also got rid of COREBOOT_COMPILER, COREBOOT_ASSEMBLER and COREBOOT_LINKER as they do not make any sense for coreboot as a whole. All these attributes are associated with each of the stages.
