2015-11-18google/veyron*: Pulse the i2c clock once if sda was lowDouglas Anderson
On one particular TV the TV was holding SDA low when it came up. It would release the SDA when the SCL went low the first time. Unfortunately the HDMI i2c port wouldn't transmit until the SDA was released. Let's detect this case and insert a bogus clock pulse to try to get the other side to release SDA. It's unclear why the kernel doesn't have this problem.

2015-11-11arm/arm64: Generalize bootblock C entry pointJulius Werner
When we first added ARM support to coreboot, it was clear that the bootblock would need to do vastly different tasks than on x86, so we moved its main logic under arch/. Now that we have several more architectures, it turns out (as with so many things lately) that x86 is really the odd one out, and all the others are trying to do pretty much the same thing. This has already caused maintenance issues as the ARM32 bootblock developed and less-mature architectures were left behind with old cruft. This patch tries to address that problem by centralizing that logic under lib/ for use by all architectures/SoCs that don't explicitly opt-out (with the slightly adapted existing BOOTBLOCK_CUSTOM option). This works great out of the box for ARM32 and ARM64. It could probably be easily applied to MIPS and RISCV as well, but I don't have any of those boards to test so I'll mark them as BOOTBLOCK_CUSTOM for now and leave that for later cleanup.

2015-09-22linking: link bootblock.elf with .data and .bss sections againAaron Durbin
Currently coreboot expects the loader to clear the bss section for all stages. i.e. stages don't clear their own bss. On ARM SoCs the BootROM would be responsible for this. To do that one needs to include the bss section data (all zeros) in the bootblock.bin file. This was previously being attempted by keeping the .bss info in the .data section because objcopy happened zero out non-file allocated data section data. Instead go back to linking bootblock with the bss section but mark the bss section as loadable allocatable data. That way it will be included in the binary properly when objcopy -O binary is emplyed. Also do the same for the data section in the case of no non-zero object values are in the data section. Without this change the trick of including .bss in .data was not working when there wasn't a non-zero value object in the data section. BUG=None BRANCH=None TEST=Built emulation/qemu-armv7 and noted bootblock.bin contains the cleared bss.

2015-09-04bootmode: add display_init_required()Aaron Durbin
Some of the Chrome OS boards were directly calling vboot called in some form after contorting around #ifdef preprocessor macros. The reasoning is that Chrome OS doesn't always do display initialization during startup. It's runtime dependent. While this is a requirement that doesn't mean vboot functions should be sprinkled around in the mainboard and chipset code. Instead provide one function, display_init_required(), that provides the policy for determining display initialization action. For Chrome OS devices this function honors vboot_skip_display_init() and all other configurations default to initializing display.

Other modes can be set to force a certain behavior such as HDMI-only on Mickey where it doesn't make sense to try EDP.

2015-06-05lib: Unify log2() and related functionsJulius Werner
This patch adds a few bit counting functions that are commonly needed for certain register calculations. We previously had a log2() implementation already, but it was awkwardly split between some C code that's only available in ramstage and an optimized x86-specific implementation in pre-RAM that prevented other archs from pulling it into earlier stages. Using __builtin_clz() as the baseline allows GCC to inline optimized assembly for most archs (including CLZ on ARM/ARM64 and BSR on x86), and to perform constant-folding if possible. What was previously named log2f on pre-RAM x86 is now ffs, since that's the standard name for that operation and I honestly don't have the slightest idea how it could've ever ended up being called log2f (which in POSIX is 'binary(2) LOGarithm with Float result, whereas the Find First Set operation has no direct correlation to logarithms that I know of). Make ffs result 0-based instead of the POSIX standard's 1-based since that is consistent with clz, log2 and the former log2f, and generally closer to what you want for most applications (a value that can directly be used as a shift to reach the found bit). Call it __ffs() instead of ffs() to avoid problems when importing code, since that's what Linux uses for the 0-based operation. CQ-DEPEND=CL:273023 BRANCH=None BUG=None TEST=Built on Big, Falco, Jerry, Oak and Urara. Compared old and new log2() and __ffs() results on Falco for a bunch of test values.

2015-04-22rockchip/rk3288: Fix operator precedence error in LPDDR initJulius Werner
Upstream coreboot regularly runs Coverity over the code base. Turns out that's a good idea since it's really easy to screw yourself over with a missing parenthesis and some unfortunately deceptive line breaking. This patch fixes a bug in LPDDR3 initialization due to an incorrect operator precedence assumption ( ?: does not bind stronger than | ). In effect, instead of setting MR11[1:0] to 0b11 or 0b00 based on ODT, we're unconditionally setting MR0[1:0] to 0b11. Thankfully, MR0[1:0] seems to contain read-only bits so this might have not been a problem when ODT is off (which is currently true for all LPDDR boards). Also adding a redundant LPDDR_OP() around the 0 to make the intent clearer and changing 3 and 0 to 0x3 and 0x0 to make it more obvious that these are bit masks (right?).

On RK3288, SRAM cannot be cached which makes the decompression so slow that it's faster to just load an uncompressed image from SPI. Disable ramstage compression on this SoC to account for that. [pg: implementation avoids restructuring all of Kconfig] BRANCH=None BUG=None TEST=Built for Pinky and Falco, confirmed that the former didn't have COMPRESS_RAMSTAGE in its .config and the latter still did. Measured a speed-up of about 35ms on Pinky. (For some weird reason, the decompression of the payload also takes way longer than on other platforms, although not as long as the ramstage. I have no explanation for that and can't really think of a good way to figure it out... maybe the Cortex-A12 is just terrible at some operation that LZMA uses a lot?)

2015-04-17rk3288: Add software I2C supportJulius Werner
This patch adds the necessary platform glue to allow the use of software-driven I2C bit banging on the RK3288. This is just a debugging feature that can be used to reproduce certain I2C failure cases. Also fix Makefile verstage linking for the feature and add some new rk3288 IOMUX macros as needed. BRANCH=None BUG=None TEST=Added "CONFIG_SOFTWARE_I2C=y" to configs/config.veyron_jerry, wrapped Jerry's bootblock and verstage in software_i2c_attach/detach() calls, confirmed that both PMIC and TPM could be driven correctly with software I2C driver. Tried out different combinations of software_i2c_wedge_ack() and software_i2c_wedge_read() on the PMIC and observed transfer results with the hardware controller after reboot... the worst that would happen is that the first register read-modify-write (DCDC_ILMAX) would fail to read, but all later transfers would be fine. Since that register is written twice (due to current BUCK1 ramp implementation) and is not terribily important anyway, I think we don't need to worry about wedging problems.

2015-04-17chromeos: Provide common watchdog reboot supportJulius Werner
Many ChromeOS devices use a GPIO to reset the system, in order to guarantee that the TPM cannot be reset without also resetting the CPU. Often chipset/SoC hardware watchdogs trigger some kind of built-in CPU reset, bypassing this GPIO and thus leaving the TPM locked. These ChromeOS devices need to detect that condition in their bootblock and trigger a second (proper) reboot. This patch adds some code to generalize this previously mainboard-specific functionality and uses it on Veyron boards. It also provides some code to add the proper eventlog entry for a watchdog reset. Since the second reboot has to happen before firmware verification and the eventlog is usually only initialized afterwards, we provide the functionality to place a tombstone in a memlayout-defined location (which could be SRAM or some MMIO register that is preserved across reboots). [pg: Integrates 'mips: Temporarily work around build error caused by <arch/io.h> mismatch] BRANCH=veyron BUG=chrome-os-partner:35705 TEST=Run 'mem w 0xff800000 0x9' on a Jerry, watch how a "Hardware watchdog reset" event appears in the eventlog after the reboot.
