2018-04-09device/dram/ddr2.c: Add methods to compute to identify dramArthur Heymans
DDR2 DIMMs are uniquely defined by SPD byte 64 till 72 and 93 till 98. Compute a crc16 over that data to provide a solid way to check DIMM identify. Reuse the crc16 function from ddr3.c to do this.

2017-12-08device/pciexp_device: Set values numerically instead of as bitmaskPatrick Georgi
As noted on linux-pci, we have a weird way to handling "value" and "scale" fields that are supposed to contain numerical values: we encode them as a bitfield. Instead define the two fields (offset and mask) and use numbers. Another issue, not fixed in this CL, is that we write hard-coded values while these fields really need to contain the max() of acceptable delays of the downstream devices. That way the controller can decide whether or not to enter a deeper power management state. It's noted as a TODO.

This further allows compilation units to be re-used without having to add macro guards because of declarations not being around in the __SIMPLE_DEVICE__ case. These declarations are for functions that operate on struct device. struct device is a known type so just expose the functions using the correct type. Also, DEVTREE_CONST is empty while in ramstage so there's no reason to separate the declarations. Lastly, fix up device_util.c to use the proper types. It's only compiled in ramstage and it only operates on struct device.

We start with four simple slave functions: i2c_readb(), i2c_writeb(), i2c_readb_at() and i2c_writeb_at(). They are all compatible to respec- tive SMBus functions.

Our current struct for I2C segments `i2c_seg` was close to being compa- tible to the Linux version `i2c_msg`, close to being compatible to SMBus and close to being readable (e.g. what was `chip` supposed to mean?) but turned out to be hard to fix. Instead of extending it in a backwards compatible way (and not touching current controller drivers), replace it with a Linux source compatible `struct i2c_msg` and patch all the drivers and users with Coccinelle. The new `struct i2c_msg` should ease porting drivers from Linux and help to write SMBus compatible controller drivers. Beside integer type changes, the field `read` is replaced with a generic field `flags` and `chip` is renamed to `slave`.

This patch uses struct device explicitly for the ramstage functions as that's the actual type it's working on. Additionally, the declarations for types and functions are fully exposed so that compliation units don't have to guard certain functions from use because it's being compiled for multiple stages.

2017-06-08device/Kconfig: Put gfx init methods into a `choice`Nico Huber
Provide all gfx init methods as a Kconfig `choice`. This elimates the option to select native gfx init along with running a Video BIOS. It's been only theoretically useful in one corner case: Hybrid graphics where only one controller is supported by native gfx init. Though I suppose in that case it's fair to assume that one would use SeaBIOS to run the VBIOS. For the case that we want the payload to initialize graphics or no pre-boot graphics at all, the new symbol NO_GFX_INIT was added to the choice. If multiple options are available, the default is chosen as follows: * NO_GFX_INIT, if we add a Video BIOS and the payload is SeaBIOS, * VGA_ROM_RUN, if we add a Video BIOS and the payload is not SeaBIOS, * NATIVE_VGA_INIT, if we don't add a Video BIOS. As a side effect, libgfxinit is now an independent choice.

The devicetree data structures have been available in more than just ramstage and romstage. In order to provide clearer and consistent semantics two new macros are provided: 1. DEVTREE_EARLY which is true when !ENV_RAMSTAGE 2. DEVTREE_CONST as a replacment for ROMSTAGE_CONST The ROMSTAGE_CONST attribute is used in the source code to mark the devicetree data structures as const in early stages even though it's not just romstage. Therefore, rename the attribute to DEVTREE_CONST as that's the actual usage. The only place where the usage was not devicetree related is console_loglevel, but the same name was used for consistency. Any stage that is not ramstage has the const C attribute applied when DEVTREE_CONST is used.

2016-12-27device/dram/ddr3: add FTB timingsNicola Corna
SPD revision 1.1 introduced FTB timings, an extra set of SPD values that specify a more precise tCKmin, tAAmin, tRCDmin, tRPmin and tRCmin. For backwards compatibility, the MTB is usually rounded up and the FTB part is negative. For this reason some memories were not set up optimally, as the FTB part was ignored and the resulting timing wasn't set to the minimum value. The tests were performed on a Lenovo X220 with two Micron 8KTF51264HZ-1G9E (1866 MHz): reading only the MTB part, coreboot reports a tCKmin of 1.125 ns, corresponding to a working frequency of 800 MHz; with the additional tCKmin FTB part (-0.054 ns) the new (rounded) value is 1.070 ns, valid for a 933 MHz operation. Tested also with Ballistix DDR3-1866 SODIMM on Lenovo T420: the memory is now detected as DDR3-1866 instead of DDR3-1600. Some manufacturers (like Micron) seems to expect a small rounding on the timings, so a nearest-value rounding is performed. If this assumption isn't correct, an error up to ~2 ps can be committed, which is low enough to be safely ignored.

Thus any feature that calls pciexp_find_extended_cap() depends on either MMCONF_SUPPORT_DEFAULT or PCI_CFG_EXT_IO being enabled on the platform. In theory there can be system without MMCONF_SUPPORT, but with complete PCI Express configuration space available using PCI_CFG_EXT_IO. Do not use explicit PCI MMCONF operations here, but rely on the default PCI access method to be able to access all of the configuration space.

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 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>
