2015-03-17coreboot classes: Add dynamic classes to corebootFurquan Shaikh
Provide functionality to create dynamic classes based on program name and the architecture for which the program needs to be compiled/linked. define_class takes program_name and arch as its arguments and adds the program_name to classes-y to create dynamic class and compiler toolset is created for the specified arch. All the files for this program can then be added to program_name-y += .. Ensure that define_class is called before any files are added to the class. Check subdirs-y for order of directory inclusion.

2015-03-13nyan: Remove broken setup_display() from romstageJulius Werner
This patch removes a chunk of romstage code from Tegra and all Nyan boards that was supposed to enable some LCD power rails early, but never really worked. The dev_find_slot() function can only find PCI devices, which the CPU cluster is not. Since we're done with Nyan-RO and the ramstage display code is fine as it is, there is no point in trying to fix this... but we should remove it from ToT lest someone uses it as a blueprint to add more dead code to future boards.

2015-03-13tegra132: fix Rx FIFO underruns with slower SPI clockAaron Durbin
The SPI controller operates on packets which can be variable length up to 32-bit packets. It also has the ability to be put in packed or unpacked mode w.r.t each packet. i.e. does a single fifo register hold >= 1 packet. The current programming uses 8-bit packets in unpacked mode which means 4 fifo slots are used for a 32-bit DMA transfter. As the AHB can only operate on a minimum of 32-bit bursts the triggers need to be programmed correctly so that there is room for a full 32-bit DMA transaction. Previously faster SPI clocks just made things magically work. BUG=chrome-os-partner:30779 BRANCH=None TEST=Built and booted through coreboot with 20MHz SPI clock.

We assume that the clock rate of SCLK/HCLK/PCLK was 408MHz which was same as PLLP. But that is incorrect, BootROM had switched it to pllp_out2 with the rate 204MHz. So actually the warm boot procedure was running at the condition of SCLK=HCLK=PCLK=pllp_out2 with the rate 204MHz.

2014-12-30tegra: i2c: Add a timeout to I2C bit clear recovery mechanismJulius Werner
Our tests with the I2C bit clear mechanism (recovering from "lost arbitration" errors) show that the bit clear hardware does not work correctly in some situations. When a wedged slave device tries to send more than one 0-to-1-to-0 transition to the host (e.g. leftover bits from an aborted read), the controller never transitions the BC_ENABLE bit back to zero. This patch adds a long timeout to the bit clear code that waits for register transitions as a safeguard. This way, We will still eventually exit the function (probably followed by a reboot). Our tests show that this will recover from all conditions after at most a few reboots.

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.

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.

2014-12-09spi: Factor EC protocol details out of the SPI drivers.Gabe Black
The SPI drivers for tegra and exynos5420 have code in them which waits for a frame header and leaves filler data out. The SPI driver shouldn't have support for frame headers directly. If a device uses them, it should support them itself. That makes the SPI drivers simpler and easier to write. When moving the frame handling logic into the EC support code, EC communication continued to work on tegra but no longer worked on exynos5420. That suggested the SPI driver on the 5420 wasn't working correctly, so I replaced that with the implementation in depthcharge. Unfortunately that implementation doesn't support waiting for a frame header for the EC, so these changes are combined into one. BUG=None TEST=Built and booted on pit. Built and booted on nyan. In both cases, verified that there were no error messages from the SPI drivers or the EC code.

2014-11-13arm: Put assembly functions into separate sectionsJulius Werner
This patch changes the ENTRY() macro in asm.h to create a new section for every assembler function, thus providing dcache_clean/invalidate_all and friends with the same --gc-sections goodness that our C functions have. This requires a few minor changes of moving around data (to make sure it ends up in the right section) and changing some libgcc functions (which apparently need to have two names?), but nothing serious. (You may note that some of our assembly functions have data, sometimes even writable, within the same .text section. This has been this way before and I'm not looking to change it for now, although it's not totally clean. Since we don't enforce read-only sections through paging, it doesn't really hurt.)

2014-11-12tegra124: enable JTAG in Security ModeJimmy Zhang
Once SECURITY_MODE fuse is burned, JTAG is disabled by default. To reenable JTAG, besides chip unique id and SecureJtagControl need to be built into BCT, Jtag enable flag is also needed to be set. BUG=None TEST=Burn SECURITY_MODE fuse, build chip specific BCT, coreboot comes up and jtag hooks up fine.
