2016-11-06elog: add sources to reflect full event type namespace usageAaron Durbin
Some events were added in other places, but coreboot's elog namespace wasn't updated. As such there's a collision with the thermtrip event. This change at least updates the elog information to reflect potential event type uage.

2016-10-24RISCV: Clean up the common architectural codeRonald G. Minnich
This version of coreboot successfully starts a Harvey (Plan 9) kernel as a payload, entering main() with no supporting assembly code for startup. The Harvey port is not complete so it just panics but ... it gets started. We provide a standard payload function that takes a pointer argument and makes the jump from machine to supervisor mode; the days of kernels running in machine mode are over. We do some small tweaks to the virtual memory code. We temporarily disable two functions that won't work on some targets as register numbers changed between 1.7 and 1.9. Once lowrisc catches up we'll reenable them. We add the PAGETABLES to the memlayout.ld and use _pagetables in the virtual memory setup code. We now use the _stack and _estack from memlayout so we know where things are. As time goes on maybe we can kill all the magic numbers.

Implement postcar stage cbmem console support. The postcar stage is more like ramstage in that RAM is already up. Therefore, in order to make the cbmem console reinit flow work one needs the cbmem init hook infrastructure in place and the cbmem recovery called. This call is added to x86/postcar.c to achieve that. Additionally, one needs to provide postcar stage cbmem init hook callbacks for the cbmem console library to use. A few other places need to become postcar stage aware so that the code paths are taken. Lastly, since postcar is backed by ram indicate that to the cbmem backing store.

2016-08-27cbmem: Always maintain backing store struct in a global on non-x86Julius Werner
The current CBMEM code contains an optimization that maintains the structure with information about the CBMEM backing store in a global variable, so that we don't have to recover it from cbmem_top() again every single time we access CBMEM. However, due to the problems with using globals in x86 romstage, this optimization has only been enabled in ramstage. However, all non-x86 platforms are SRAM-based (at least for now) and can use globals perfectly fine in earlier stages. Therefore, this patch extends the optimization on those platforms to all stages. This also allows us to remove the requirement that cbmem_top() needs to return NULL before its backing store has been initialized from those boards, since the CBMEM code can now keep track of whether it has been initialized by itself.

2016-08-27cbfs: Add "struct" file type and associated helpersJulius Werner
This patch adds functionality to compile a C data structure into a raw binary file, add it to CBFS and allow coreboot to load it at runtime. This is useful in all cases where we need to be able to have several larger data sets available in an image, but will only require a small subset of them at boot (a classic example would be DRAM parameters) or only require it in certain boot modes. This allows us to load less data from flash and increase boot speed compared to solutions that compile all data sets into a stage. Each structure has to be defined in a separate .c file which contains no functions and only a single global variable. The data type must be serialization safe (composed of only fixed-width types, paying attention to padding). It must be added to CBFS in a Makefile with the 'struct' file processor.

2016-07-13tpm2: use pcr0 dependent nvram space policy definitionsVadim Bendebury
The TPM2 specification allows defining NV ram spaces in a manner that makes it impossible to remove the space until a certain PCR is in a certain state. This comes in handy when defining spaces for rollback counters: make their removal depend on PCR0 being in the default state. Then extend PCR0 to any value. This guarantees that the spaces can not be deleted. Also, there is no need t create firmware and kernel rollback spaces with different privileges: they both can be created with the same set of properties, the firmware space could be locked by the RO firmware, and the kernel space could be locked by the RW firmware thus providing necessary privilege levels.

This patch adds a TPM2 specific path in the vboot2 initialization sequence when the device is turned on in the factory for the first time, namely two secure NVRAM spaces are created, with different access privileges. The higher privilege space can be modified only be the RO firmware, and the lower privilege space can be modified by both RO and RW firmware. The API is being modified to hide the TPM implementation details from the caller. Some functions previously exported as global are in fact not used anywhere else, they are being defined static.

2016-07-11tpm2: implement tlcl layerVadim Bendebury
This is the first approximation of implementing TPM2 support in coreboot. It is very clearly incomplete, some of the larger missing pieces being: - PCR(s) modification - protection NVRAM spaces from unauthorized deletion/modification. - resume handling - cr50 specific factory initialization The existing TPM1.2 firmware API is being implemented for TPM2. Some functions are not required at all, some do not map fully, but the API is not yet being changed, many functions are just stubs. An addition to the API is the new tlcl_define_space() function. It abstracts TMP internals allowing the caller to specify the privilege level of the space to be defined. Two privilege levels are defined, higher for the RO firmware and lower for RW firmware, they determine who can write into the spaces.

2016-06-09device: i2c: Add support for I2C bus operationsDuncan Laurie
In order to support doing bus operations on an I2C device that is described in the devicetree there needs to be some linkage of the device and the existing opaque I2C controller bus number. This is provided in a similar fashion to the existing SMBUS operations but modified to fit within the existing I2C infrastructure. Variants of the existing I2C helper functions are provided that will obtain the bus number that corresponds to this device by looking for the SOC-provided I2C bus operation structure to provide a function that will make that translation. For example an SOC using a PCI I2C controller at 0:15.0 could use: soc/intel/.../i2c.c: static int i2c_dev_to_bus(struct device *dev) { if (dev->path.pci.devfn == PCI_DEVFN(0x15, 0)) return 0; return -1; } static struct i2c_bus_operation i2c_bus_ops = { .dev_to_bus = &i2c_dev_to_bus } static struct device_operations i2c_dev_ops = { .ops_i2c_bus = &i2c_bus_ops ... } With an I2C device on that bus at address 0x1a described in the tree: devicetree.cb: device pci 15.0 on # I2C0 chip drivers/i2c/sample device i2c 1a.0 on end end end That driver can then do I2C transactions with the device object without needing to know that the SOC-specific bus number that this I2C device lives on is "0". For example it could read a version value from register address 0 with a byte transaction: drivers/i2c/sample/sample.c: static void i2c_sample_enable(struct device *dev) { uint8_t ver; if (!i2c_dev_readb(dev, 0x00, &ver)) printk(BIOS_INFO, "I2C %s version 0x02x\n", dev_path(dev), ver); } Change-Id: I6c41c8e0d10caabe01cc41da96382074de40e91e Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/15100 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>

Add a new function "gpio_acpi_path()" that can be implemented by SoC/board code to provide a mapping from a "gpio_t" pin to a controller by returning the ACPI path for the controller that owns this particular GPIO. This is implemented separately from the "acpi_name" handler as many SOCs do not have a specific device that handles GPIOs (or may have many devices and the only way to know which is the opaque gpio_t) and the current GPIO library does not have any association with the device tree. If not implemented (many SoCs do not implement the GPIO library abstraction at all in coreboot) then the default handler will return NULL and the caller knows it cannot determine this reliably.

2016-05-21device: Add an ACPI device name and path concept to devicesDuncan Laurie
Add a function to "struct device_operations" to return the ACPI name for the device, and helper functions to find this name (either from the device or its parent) and to build a fully qualified ACPI path from the root device. This addition will allow device drivers to generate their ACPI AML in the SSDT at boot, with customization supplied by devicetree.cb, instead of needing custom DSDT ASL for every mainboard. The root device acpi_name is defined as "\\_SB" and is used to start the path when building a fully qualified name. This requires SOC support to provide handlers for returning the ACPI name for devices that it owns, and those names must match the objects declared in the DSDT. The handler can be done either in each device driver or with a global handler for the entire SOC. Simplified example of how this can be used for an i2c device declared in devicetree.cb with: chip soc/intel/skylake # "\_SB" (from root device) device domain 0 on # "PCI0" device pci 19.2 on # "I2C4" chip drivers/i2c/test0 device i2c 1a.0 on end # "TST0" end end end end And basic SSDT generating code in the device driver: acpigen_write_scope(acpi_device_scope(dev)); acpigen_write_device(acpi_device_name(dev)); acpigen_write_string("_HID", "TEST0000"); acpigen_write_byte("_UID", 0); acpigen_pop_len(); /* device */ acpigen_pop_len(); /* scope */ Will produce this ACPI code: Scope (\_SB.PCI0.I2C4) { Device (TST0) { Name (_HID, "TEST0000") Name (_UID, 0) } } Change-Id: Ie149595aeab96266fa5f006e7934339f0119ac54 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/14840 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>

This patch makes it explicitly configurable and depends the default on ARCH_X86 (which seems to be the simplest and least intrusive way to make it fit most cases for now... boards where this doesn't apply can still override it manually by calling edid_set_framebuffer_bits_per_pixel() again).

2016-03-29cbmem: Add comment for cbmem_top returning NULL if backing store is not readyFurquan Shaikh
Board or chipset needs to ensure that cbmem backing store is ready when returning the cbmem top address. cbmem infrastructure has no support for checking the validity of the backing store/address. E.g.: If romstage handles cbmem coming online, chipset or board need to ensure that call to cbmem_top in romstage returns NULL if the backing store is not yet initialized. Add a comment to ensure that developers know this requirement while implementing cbmem_top for future chipsets/boards.

2016-03-24edid: Add helper function to calculate bits-per-pixel dependent valuesJulius Werner
Coreboot and most payloads support three basic pixel widths for the framebuffer. It assumes 32 by default, but several chipsets need to override that value with whatever else they're supporting. Our struct edid contains multiple convenience values that are directly derived from this (and other properties), so changing the bits per pixel always requires recalculating all those dependents in the chipset code. This patch provides a small convenience wrapper that can be used to consistently update the whole struct edid with a new pixel width instead, so we no longer need to duplicate those calculations everywhere. BUG=None TEST=Booted Oak in all three pixel widths (which it conveniently all supports), confirmed that images looked good.

2016-03-23arch/x86: introduce postcar stage/phaseAaron Durbin
Certain chipsets don't have a memory-mapped boot media so their code execution for stages prior to DRAM initialization is backed by SRAM or cache-as-ram. The postcar stage/phase handles the cache-as-ram situation where in order to tear down cache-as-ram one needs to be executing out of a backing store that isn't transient. By current definition, cache-as-ram is volatile and tearing it down leads to its contents disappearing. Therefore provide a shim layer, postcar, that's loaded into memory and executed which does 2 things: 1. Tears down cache-as-ram with a chipset helper function. 2. Loads and runs ramstage. Because those 2 things are executed out of ram there's no issue of the code's backing store while executing the code that tears down cache-as-ram. The current implementation makes no assumption regarding cacheability of the DRAM itself. If the chipset code wishes to cache DRAM for loading of the postcar stage/phase then it's also up to the chipset to handle any coherency issues pertaining to cache-as-ram destruction.

2016-03-22gpio: Add support for binary_first base3 number systemJulius Werner
This patch adds support for an alternative ternary number system in which group of GPIOs can be interpreted. In this system, the digit combinations that would form a binary number (i.e. that contain no 'Z' state) are used to represent the lower values in the way they're used in the normal binary system, and all the combinations that do contain a 'Z' are used to represent values above those. We can use this for boards that originally get strapped with binary board IDs but eventually require more revisions than that representation allows. We can switch their code to binary_first base3 and all old revisions with already produced boards will still get read as the correct numbers. Credit for the algorithm idea goes to Haran Talmon. BRANCH=None BUG=None TEST=Stubbed out the actual GPIO reading and simulated all combinations of 4 ternary digits for both number systems.
