The medany code model gets around this restriction by loading pointers trough auipc and addi: auipc a0, 0xNNNNN addi a0, a0, 0xNNN This way, any pointer within the current pc ±2G can be loaded, which is by far sufficient for coreboot.

2016-06-12Kconfig: Set VBOOT_OPROM_MATTERS for relevant non-x86 devicesJulius Werner
The VBOOT_OPROM_MATTERS configuration option signals to vboot that the board can skip display initialization in the normal boot path. It's name is a left-over from a time when this could only happen by avoiding loading the VGA option ROM on x86 devices. Now we have other boards that can skip their native display initialization paths too, and the effect to vboot is the same. (Really, we should rename oprom_matters and oprom_loaded to display_skippable and display_initialized or something, but I don't think that's worth the amount of repositories this would need to touch.) The only effect this still has in today's vboot is to reboot and explicitly request display initialization for EC software sync on VBOOT_EC_SLOW_UPDATE devices (which we haven't had yet on ARM). Still, the vboot flag just declares the capability (for skipping display init), and it should be set correctly regardless of whether that actually makes a difference on a given platform (right now). This patch updates all boards/SoCs that have a conditional path based on display_init_required() accordingly. BRANCH=None BUG=chrome-os-partner:51145 TEST=Booted Oak, confirmed that there's no notable boot time impact.

Support the common Intel LPSS I2C driver for the 6 I2C bus controllers that are present on the Skylake-LP PCH with a 120 mHz clock. The required lpss_i2c_base_address() method is implemented separately for verstage/romstage and ramstage environments. This provides methods to convert to and from "struct device" and the I2C controller bus number for that device. These are used to provide support for the "I2C Bus Operations" that are present in the coreboot devicetree. To support the I2C controller before ramstage an early init function is provided to do minimal initializaiton of the PCI device and assign a temporary base address for use before memory. The final base address is assigned during device enumeration and used during ramstage. Because it is usually not necessary to enable I2C controllers before ramstage a config register for the devicetree is provided to perform early initialization of this controller. In addition the bus speed can be set in the devicetree and that speed will be applied when the device is initialized. If not provided the default speed is set to I2C_SPEED_FAST. This was tested with the google/chell mainboard by reading and writing from the trackpad and codec devices during both verstage and ramstage.

Add the voltage tolerance GPIO attribute for configuring I2C/I2S buses that are at 1.8V. This is currently done by passing in a value to FSP but it is needed earlier than FSP if the I2C bus is used in verstage. This does not remove the need for the FSP input parameter, that is still required so FSP doesn't disable what has been set in coreboot. The mainboards that are affected are updated in this commit. This was tested by exercising I2C transactions to the 1.8V codec while in verstage on the google/chell mainboard.

2016-06-09soc/intel/common: Add LPSS I2C driverDuncan Laurie
Add a generic LPSS I2C driver for Intel SOCs that use the Synopsys DesignWare I2C block and have a similar configuration of that block. This driver is ported from the Chromium depthcharge project where it was ported from U-Boot originally, though it looks very different now. From depthcharge it has been modified to fit into the coreboot I2C driver model with platform_i2c_transfer() and use coreboot semantics throughout including the stopwatch API for timeouts. In order for this shared driver to work the SOC must: 1) Define CONFIG_SOC_INTEL_COMMON_LPSS_I2C_CLOCK_MHZ to set the clock speed that the I2C controller core is running at. 2) Define the lpss_i2c_base_address() function to return the base address for the specified bus. This could be either done by looking up the PCI device or a static table if the controllers are not PCI devices and just have a static base address. The driver is usable in verstage/romstage/ramstage, though it does require early initialization of the controller to set a temporary base address if it is used outside of ramstage. This has been tested on Broadwell and Skylake SOCs in both pre-RAM and ramstage environments by reading and writing both single bytes across multiple segments as well as large blocks of data at once and with different configured bus speeds. While it does need specific configuration for each SOC this driver should be able to work on all Intel SOCs currently in src/soc/intel.

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>

Setting the size of the preallocated memory for the igd is done using a cmos parameter, gfx_uma_size. This was limited to a subset of all available sizes, that were already implemented elsewhere in the northbridge code. What this does is change the cmos parameter to 4 bits instead of 3 bits to accomodate all vram sizes. It also adds a sane default of 32mb that already was in place. The northbridge code that reads this cmos parameter is also changed for this new cmos settings. 352M is disabled since it causes issues on systems with 4GB or more ram. TEST: Build, flash target. Clear cmos by corrupting the checksum (nvramtool -c something). Set a desired value in gfx_uma_size using nvramtool. "dmesg | grep stolen" to see what is actually allocated.

2016-06-02generic: Add a Maxim 98357A codec driverDuncan Laurie
The Maxim Integrated 98357A codec is an I2S slave device that has no control channel for configuration and instead provides a GPIO that is used for channel selection and power down. This means it does not fit into a bus hierarchy easily and is instead represented as a generic device and found with a static bus scan using the devicetree. This driver provides configuration options for passing the "sdmode" GPIO descriptor as well as a second option for "sdmode delay" which can configure the timing of the sdmode toggling in relation to the I2S channel output. In addition an GPIO can be provided to indicate to the driver whether this device is present or not. This can be used for board designs that may have different codec possibilities that are selected by HW strap. Sample usage for this device driver: device pci 1f.3 on chip drivers/generic/max98357a register "sdmode_gpio" = "ACPI_GPIO_OUTPUT(GPP_C6)" register "sdmode_delay" = "100" device generic 0 on end end end Will result in the following code in the SSDT: Scope (\_SB.PCI0.HDAS) { Device (MAXM) { Name (_HID, "MX98357A") Name (_UID, Zero) Name (_DDN, "Maxim Integrated 98357A Amplifier") Method (_STA) { Return (0xF) } Name (_CRS, ResourceTemplate () { GpioIo (Exclusive, PullDefault, 0, 0, IoRestrictionOutputOnly, "\\_SB.PCI0.GPIO", 0, ResourceConsumer) }) Name (_DSD, Package () { ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"), Package () { Package () { "maxim,sdmode-gpio", \_SB.PCI0.HDAS.MAXM, 0, 0, 0 } Package () { "maxim,sdmode-delay", 100 } Package () { "sdmode-delay", 100 } } }) } } Change-Id: Ia0bafe49bea9bbe4a3cc0f9f9cdb6f6390da57b5 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/15017 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>
2016-06-02i2c: Add a generic i2c driverDuncan Laurie
This adds a generic I2C driver that can be described in the devicetree and used to generate ACPI objects in the SSDT based on the information provided in the config registers. The I2C bus can be configured and the device can provide an interrupt and wake capability to the OS. A configuration option allows for a GPIO to be provided that will be checked to determine if the device is preset on the board before including it in the generated SSDT. The driver is generic enough to be used for basic I2C devices that do not have special configuration needs such as touchpads, touchscreens, sensors, some audio codec/amplifiers, etc. Sample usage for a touchpad device: device pci 15.1 on chip drivers/i2c/generic register "hid" = ""ELAN0000"" register "desc" = "ELAN Touchpad" register "irq" = "IRQ_EDGE_LOW(GPP_B3_IRQ)" register "wake" = "GPE0_DW0_05" device i2c 15.0 on end end end Will result in the following code in the SSDT: Scope (\_SB.PCI0.I2C1) { Device (D015) { Name (_HID, "ELAN0000") Name (_UID, 0) Name (_S0W, 4) Name (_PRW, Package () { 5, 3 }) Method (_STA) { Return (0x0f) } Name (_CRS, ResourceTemplate () { I2cSerialBus (0x15, ControllerInitiated, 400000, AddressingMode7Bit, "\\_S.PCI0.I2C1", 0, ResourceConsumer) Interrupt (ResourceConsumer, Edge, ActiveLow) { 51 } }) } } Change-Id: Ib32055720835b70e91ede5e4028ecd91894d70d5 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/15016 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>
