2017-08-09device/pci: untangle struct device and device_tAaron Durbin
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.

2017-04-25lib: provide clearer devicetree semanticsAaron Durbin
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.

2016-06-09device: 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>
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>
2016-05-16sconfig: Add a new generic device typeDuncan Laurie
Add support for a basic generic device in the devicetree to bind to a device that does not have a specific bus, but may need to be described in tables for the operating system. For instance some chips may have various GPIO connections that need described but do not fall under any other device. In order to support this export the basic 'scan_static_bus()' that can be used in a device_operations->scan_bus() method to scan for the generic devices. It has been possible to get a semi-generic device by using a fake PNP device, but that isn't really appropriate for many devices. Also Re-generate the shipped files for sconfig. Use flex 2.6.0 to avoid everything being rewritten. Clean up the local paths that leak into the generated configs.

2013-11-08Add new finalize functions for devices and chipsMarc Jones
Many chipset devices require additional configuration after device init. It is not uncommmon for a device early in the devicetree list to need to change a setting after a device later in the tree does PCI init. A final function call has been added to device ops to handle this case. It is called prior to coreboot table setup. Another problem that is often seen is that the chipset or mainboard need to do some final cleanup just before loading the OS. The chip finalize has been added for this case. It is call after all coreboot tables are setup and the payload is ready to be called. Similar functionality could be implemented with the hardwaremain states, but those don't fit well in the device tree function pointer structure and should be used sparingly.

The IORESOURCE_UMA_FB and IORESOURCE_IGNORE_MTRR attributes on a resource provided hints to the MTRR algorithm. The IORESOURCE_UMA_FB directed the MTRR algorithm to setup a uncacheable space for the resource. The IORESOURCE_IGNORE_MTRR directed the MTRR algorithm to ignore this resource as it was used reserving RAM space. Now that the optimizing MTRR algorithm is in place there isn't a need for these flags. All IORESOURCE_IGNORE_MTRR users are handled by the MTRR code merging resources of the same cacheable type. The users of the IORESOURCE_UMA_FB will find that the default MTRR type calculation means there isn't a need for this flag any more.

2012-08-04Make the device tree available in the rom stageStefan Reinauer
We thought about two ways to do this change. The way we decided to try was to 1. drop all ops from devices in romstage 2. constify all devices in romstage (make them read-only) so we can compile static.c into romstage 3. the device tree "devices" can be used to read configuration from the device tree (and nothing else, really) 4. the device tree devices are accessed through struct device * in romstage only. device_t stays the typedef to int in romstage 5. Use the same static.c file in ramstage and romstage We declare structs as follows: ROMSTAGE_CONST struct bus dev_root_links[]; ROMSTAGE_CONST is const in romstage and empty in ramstage; This forces all of the device tree into the text area. So a struct looks like this: static ROMSTAGE_CONST struct device _dev21 = { #ifndef __PRE_RAM__ .ops = 0, #endif .bus = &_dev7_links[0], .path = {.type=DEVICE_PATH_PCI,{.pci={ .devfn = PCI_DEVFN(0x1c,3)}}}, .enabled = 0, .on_mainboard = 1, .subsystem_vendor = 0x1ae0, .subsystem_device = 0xc000, .link_list = NULL, .sibling = &_dev22, #ifndef __PRE_RAM__ .chip_ops = &southbridge_intel_bd82x6x_ops, #endif .chip_info = &southbridge_intel_bd82x6x_info_10, .next=&_dev22 }; Change-Id: I722454d8d3c40baf7df989f5a6891f6ba7db5727 Signed-off-by: Ronald G.

2009-07-02Move the v3 resource allocator to v2.Myles Watson
Major changes: 1. Separate resource allocation into: A. Read Resources B. Avoid fixed resources (constrain limits) C. Allocate resources D. Set resources Usage notes: Resources which have IORESOURCE_FIXED set in the flags constrain the placement of other resources. All fixed resources will end up outside (above or below) the allocated resources. Domains usually start with base = 0 and limit = 2^address_bits - 1. I've added an IOAPIC to all platforms so that the old limit of 0xfec00000 is still there for resources. Some platforms may want to change that, but I didn't want to break anyone's board. Resources are allocated in a single block for memory and another for I/O. Currently the resource allocator doesn't support holes. Signed-off-by: Myles Watson <mylesgw@gmail.com> Acked-by: Ronald G.

2008-02-01 This patch fixes the decoding of the IO address range 0x0820->0x0827 into theFlorentin Demetrescu
LPC device of the MCP55 southbridge, thus enabling flashrom access to the SPI interface of the IT8716 SIO chip. Changes : 1) - increase MAX_RESOURCES to 24 in device.h -> this was needed because some functions of a PNP device can have more than 12 resources (ex the GPIO function of IT8716f), in which case one could have an "array overflow" inside the device structure (yes gcc is stupid!..) and ultimately a disaster (fool pointer at device init time..) 2) - define resource masks for the GPIO function in src/superio/ite/it8716f/superio.c -> this is needed because otherwise the IO ranges which are set into the LPC bridge of the SB are very strange (f.ex.: 0x800->0x7ff and so on..). Problem: the PNP_IO0 resource is not defined for the GPIO function, thus we have to define a "fake" mask "{0,0}" to avoid mismatching by the init code 3) - enable the flash SPI interface into src/mainboard/gigabyte/m57sli/Config.lb (by enabling the corresponding resource into the GPIO function). I know that this is problematic because not all m57sli boards are SPI, but .. do anyone have a better idea how to handle this?.. Signed-off-by: Florentin Demetrescu <echelon@free.fr> I (Ward) have verified your patch on a rev2 of this board (it works!) as well as on a rev1 (plcc). It does not affect flashing on rev1 nor have any averse side effects that I noticed, so I think this patch should go in.
