2014-09-08ARM: Generalize armv7 as arm.Gabe Black
There are ARM systems which are essentially heterogeneous multicores where some cores implement a different ARM architecture version than other cores. A specific example is the tegra124 which boots on an ARMv4 coprocessor while most code, including most of the firmware, runs on the main ARMv7 core. To support SOCs like this, the plan is to generalize the ARM architecture so that all versions are available, and an SOC/CPU can then select what architecture variant should be used for each component of the firmware; bootblock, romstage, and ramstage.

We don't always want to use ARMv7 code when building for ARM, so we should separate out the ARMv7 code so it can be excluded, and also make it possible to include code for some other version of the architecture instead, all per build component for cases where we need more than one architecture version at a time. The tegra124 bootblock will ultimately need to be ARMv4, but until we have some ARMv4 code to switch over to we can leave it set to ARMv7.

2014-08-29tegra124: add custom uartGabe Black
tegra124: Add a test function which spams exclamation points on the UART. This function spews characters on the console and, until we have a working console, is an easy way to see whether the system boots to a particular point. For some reason waiting for transmitter to be empty hangs, but transmitting characters still works.

Now that the bootblock is compiled with more appropriate flags, this code can be re-introduced.

2014-08-19tegra124: Implement driver code for the pinmux, pingroup controls, and GPIOs.Gabe Black
The pins on tegra are controlled by three different units, the pinmux, the pin group controls, and the GPIO banks. Each of these units controls some aspect of the pins, and they layer together and interact in interesting ways. By default, the GPIOs are configured to pass through the special purpose IO that the pinmux is configured to and so can be ignored unless a GPIO is needed. The pinmux controls which special purpose signal passes through, along with pull ups, downs, and whether the output is tristated. The pingroup controls change the parameters of a group of pins which all have to do with a related function unit. The enum which holds constants related to the pinmux is relatively involved and may not be entirely complete or correct due to slightly inconsistent, incomplete, or missing documentation related to the pinmux. Considerable effort has been made to make it as accurate as possible. It includes a constant which is the index into the pinmux control registers for that pin, what each of the functions supported by that pin are, and which GPIO it corresponds to. The GPIO constant is named after the GPIO and is the pinmux register index for the pin for that GPIO. That way, when you need to turn on a GPIO, you can use that constant along with the pinmux manipulating functions to enable its tristate and pull up/down mode in addition to setting up the GPIO controls. Also, while in general I prefer not to use macros or the preprocessor when writing C code, in this case the set of constants in the enums was too large and cumbersome to manage without them. Since they're being used to construct a table in a straightforward way, hopefully their negative aspects will be minimized. In addition to the low level functions in each driver, the GPIO code also includes some high level functions to set up input or output GPIOs since that will probably be a very common thing to want to do.

2014-08-18tegra: Change how tegra124 and tegra include files from each other.Gabe Black
A problem with including the tegra124 directory directly in the include path is that it makes all headers in that directory first level headers available everywhere including places that have nothing to do with the SOC, even headers which were only intended for local use by tegra124 code. This change modifies things a bit to be more like the way the arch headers are chosen. In the tegra124 directory, there's an include directory which has an soc subdirectory in it. That include directory is added to the include path, making it possible to have headers private to the tegra124. When files specific to whatever tegra is being built for are needed, you can include <soc/foo.h> and get the version specific to that particular soc. Also, the soc.h header file was overhauled to use enums instead of defines, to consistently name things as far as their prefix (the less cryptic TEGRA instead of NV_PA) and suffixes like "BASE", and to get rid of values which were specific to U-Boot which we don't need. Since the only thing in the file were address constants, I also renamed the file addressmap.h. It would be included as: <soc/addressmap.h> which I think is easy to remember, does what you'd think it does from the name, and won't conflict with other header files just minding their own business in some other directory.

2014-08-13Tegra,Tegra124: proposed layout for file hierarchy with exampleRonald G. Minnich
This change shows the source structure for nvidia Tegra and Tegra124 SOC. The problem we are trying to solve is that there is a large amount of common code in the form of .c and .h files across many different Tegra SOCs. The solution is to provide common code in a single directory, but not to compile in the common code directory; rather, we compile in a directory for a given SOC. Different SOCs will sometimes need different bits of code from the common directory. Tegra common code lives in tegra/, but there is no makefile there: if a Tegra common file is needed in a SOC, it is referenced via a Makefile in a specific Tegra SOC. Another issue is includes. Include files in the common directory might be accessed by a piece of code in an SOC directory. More problematically, code in the common directory might require a file in an SOC directory. We don't want to put the SOC name in an #include path, e.g. in a C file in tegra/ is very undesirable, since we might be compiling for a tegra114. On some systems this is solved by a pre-pass which creates a set of symbolic links; on others with nested #ifdef in the common code which include different .h files depending on CPP variables. In previous years, both LinuxBIOS and coreboot have tried these solutions and found them inconvenient and error-prone. We choose to solve it by requiring explicit naming of part of the path of files that are in the common directory. This requirement, coupled with two -I directives in the Makefile.inc, allows common and SOC C code to incorporate both common and SOC .h files. .c and .h files -- SOC or common -- name include files in the common directory with the prefix tegra/, e.g. SOC files will be included from the SOC directory if they have no prefix: The full patch of clock.h will depend on what SOC is being compiled, which is desirable. In this way, a common file can pick up a specific SOC file without creating symlinks or other such tricky magic. We show this usage with one file, soc/nvidia/tega124/clock.c. This compiles. The last question is where to put the prototype for the function defined in this file -- soc.h? Change-Id: Iecb635cec70f24a5b3e18caeda09d04a00d29409 Signed-off-by: Ronald G.

2014-08-01fsp_baytrail/.../gpio.h: Add GPIO_NC1 for GPIOS on func 1Martin Roth
The GPIO_NC setting sets up the gpio as a no-connect - sets it as an input, and pulls it high. It makes an assumption that the GPIO function is muxing function 0. There are a few GPIOs that are on function 1 instead: * GPIO_S0_SC[092-93] * GPIO_S5[11-21] For these GPIOs, use the GPIO_NC1 setting instead of GPIO_NC.

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.

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.

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.
