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.
