2015-02-05drivers/xgi/z9s: Port Linux framebuffer initialization to corebootTimothy Pearson
Add native XGI Z9s framebuffer support to coreboot XGI initialization code largely taken from Linux 3.18.5 TEST: Booted KFSN4-DRE with XGI Volari Z9s into SeaBIOS with SeaVGABIOS enabled. Text appeared correctly on screen and interaction with graphical comboot menu was successful. However, Linux cleared the framebuffer on boot, rendering the screen useless until Linux loaded its native xgifb driver.

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. BRANCH=None BUG=chrome-os-partner:28323 TEST=Spread tegra_software_i2c_init()/tegra_software_i2c_disable() through the code and see that everything still works.

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.

2014-12-15tegra124: A couple clock fixes.Gabe Black
This fixes two problems with the clock configuration on tegra124. First, the macro which set up the i2c clocks tried to account for the fact that the i2c divisor's lsb represents 1.0 where it normally represents 0.5 by multiplying the target frequency by 2. That doesn't work, unfortunately, because the divisor is actually n + 1, and what n + 1 means depends on where the one's place is in the divisor. Also, when calculating the divisor, the standard C division operator uses truncation to deal any remainder which tends to make the divisor smaller. That has the effect of making the output frequency higher than what was requested. Since it's usually safer to undershoot a frequency than overshoot it, this change makes those divisions round up instead. Finally, the hand tuned temporary UART clock configuration was adjusted so that it still ends up with the same divisor. Without that, very early output from the bootblock is garbled, specifically the coreboot welcome banner, build timestamp, etc. BUG=chrome-os-partner:27220 TEST=Built and booted on nyan. Used a logic analyzer to verify that the TPM i2c bus ran at 400KHz instead of 660KHz, and that the divisor was the expected value. Measured boot time with and without EFS and verified that there was no change. Spot checked the output for errors and verified that none of the bootblock output was garbled. BRANCH=None Had to add the stdlib.h from 89ed6c that hadn't been merged correctly.
