2014-12-30i2c: Add software_i2c driver for I2C debugging and emulationJulius Werner
This patch adds I2C emulation in software through raw toggling of the SDA/SCL lines. Platforms need to provide bindings to toggle their respective I2C busses for this to work (e.g. by pinmuxing them as GPIOs, currently only enabled for Tegra). This is mostly useful as a debugging feature, to drive unusual states on a bus and closely monitor the device output without the need of a bus analyzer. It provides a few functions to "wedge" an I2C bus by aborting a transaction at certain points, which can be used to test if a system can correctly recover from an ill-timed reboot. However, it can also dynamically replace the existing I2C transfer functions and drive some/all I2C transfers on the system, which might be useful if a driver for the actual I2C controller hardware is not (yet) available. Based on original code by Doug Anderson <dianders@chromium.org> and Hung-ying Tyan <tyanh@chromium.org> for the ChromeOS embedded controller project.

2014-12-16i2c: Replace the i2c API.Gabe Black
The new API is in use in depthcharge and is based around the "i2c_transfer" function instead of i2c_read and i2c_write. The new function takes an array of i2c_seg structures which represent each portion of the transfer after a start bit and before the stop bit. If there's more than one segment, they're seperated by repeated starts. Some wrapper functions have also been added which make certain common operations easy. These include reading or writing a byte from a register or reading or writing a blob of raw data. The i2c device drivers generally use these wrappers but can call the i2c_transfer function directly if the need something different. The tegra i2c driver was very similar to the one in depthcharge and was simple to convert. The Exynos 5250 and 5420 drivers were ported from depthcharge and replace the ones in coreboot. The Exynos 5420 driver was ported from the high speed portion of the one in coreboot and was straightforward to port back. The low speed portion and the Exynos 5250 drivers had been transplanted from U-Boot and were replaced with the depthcharge implementation. BUG=None TEST=Built and booted on nyan with and without EFS.

2014-07-19device/pci_early.c: Mixes up variants of a typedefs to 'u32'Edward O'Callaghan
Unfortunately coreboot has to deal with ROMCC's short comings which has lead to a little bit of confusion due to typedefs. Essentially, coreboot defines four typedefs: * 'typedef struct device * device_t' in ramstage not in SIMPLE_DEVICE mode * 'typedef u32 device_t' in romstage or when SIMPLE_DEVICE is defined * 'typedef u32 pnp_devfn_t' * 'typedef u32 pci_devfn_t' Some early functions make use of 'device_t' over 'pci_devfn_t' and since the C type-checker does not enforce typedefs to the same type 'u32' these are never noticed. Fix these so that 'device_t' does not conflict in romstage for later work. We later plan to have 'pnp_devfn_t' and 'pci_devfn_t' as the only variants of 'u32' and 'device_t' to be a struct pointer type exclusively.

2014-05-29PCI IRQs: Swizzle PCI IRQs for PCI bridgesMike Loptien
The PCI Specification states that devices that implement a bridge and a secondary bus must swizzle (rotate) the interrupt pins according to the table below: Child Dev # Child PIN Parent PIN 0,4,8,12... A/B/C/D A/B/C/D 1,5,9,13... A/B/C/D B/C/D/A 2,6,10,14.. A/B/C/D C/D/A/B 3,7,11,15.. A/B/C/D D/A/B/C Which is also described by this equation: PIN_parent = (Pin_child + Dev_child) % 4 When a device is found and its bus number is greater than 0, it is on a bridge and needs to be swizzled. Following the string of parents up to the root bus and swizzling as we go gives us the desired swizzling result. When BIOS_SPEW is defined, it will print out each step of the swizzling process.

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 current default implementation of pnp_enable() only disables devices - if set so in the devicetree - but does not enable them. Enablement takes place in pnp_enable_resources(). Yet, many PnP chips implement their own version of pnp_enable() which also enables devices if set in the devicetree. It's arguable, if enabling those devices makes sense, before they get resources assigned. Maybe we can't write the resource registers if not, who knows? The least we can do is providing a common implementation for this behavior, and get rid of some code duplication.

We're not a command-line utility. - Let the compiler place static variables automatically. We don't need any of this fancy manual data placement. - Remove dead code while we're at it. This stuff was ported early on and much of it was left commented out in case we needed it. Some also includes nested macros which caused gcc to complain. - Clean up #includes (no more common.h, woohoo!), replace debug() with printk().

2013-04-09replace device/i2c.h with simpler versionDavid Hendricks
The existing header was imported along with the Exynos code and left mostly unchanged. This is the first patch in a series intended to replace the imported u-boot I2C API with a much simpler and cleaner interface: - We only need to expose i2c_read() and i2c_write() in our public API. Everything else is board/chip-dependent and should remain hidden away. - i2c_read and i2c_write functions will take bus number as an arg and we'll eliminate i2c_get_bus and i2c_set_bus. Those are prone to error and end up cluttering the code since the user needs to save the old bus number, set the new one, do the read/write, and restore the old value (3 added steps to do a simple transaction). - Stop setting default values for board-specific things like SPD and RTC bus numbers (as if we always have an SPD or RTC on I2C). - Death to all the trivial inline wrappers. And in case there was any doubt, we really don't care about the MPC8xx. Though if we did then we would not pollute the public API with its idiosyncrasies.

2013-03-29resources: remove IORESOURCE_[UMA_FB|IGNORE_MTRR]Aaron Durbin
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.

Instead, be more explicit for those uses with reserved_ram_resource(). bad_ram_resource() now calls reserved_ram_resource(). Those resources are marked as cacheable but reserved.

Here's the great news: From now on you don't have to worry about hitting the right io.h include anymore. Just forget about romcc_io.h and use io.h instead. This cleanup has a number of advantages, like you don't have to guard device/ includes for SMM and pre RAM anymore. This allows to get rid of a number of ifdefs and will generally make the code more readable and understandable. Potentially in the future some of the code in the io.h __PRE_RAM__ path should move to device.h or other device/ includes instead, but that's another incremental change.

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.
