2019-10-24drivers/ipmi: Add IPMI BMC FRB2 watchdog timer supportJohnny Lin
Add a function for initializing and starting FRB2 timer with the provided countdown and action values, and a stop function for stopping the timer. Tested on OCP Monolake.

2019-10-24drivers/i2c/rt1011: Add a driver for RT1011Cheng-Yi Chiang
RT1011 is a smart amplifier. It needs to know speaker related parameters including speaker resistor value and temperature when the calibration is done in order to run Dynamic Speaker Management (DSM) algorithm on chip. The purpose of DSM is to protect speaker when the volume is large. The calibration data of speaker is stored in VPD in factory. This driver is needed to read data from VPD and write to ACPI _DSD when config CHROMEOS_DSM_CALIB is turned on. Kernel rt1011 codec driver will read these device properties to set up codec accordingly on boot. The reason to prepare these parameters in coreboot is because kernel codec driver expects to read per-device parameters directly from device properties. Another benefit is that other OS can also take these parameters through ACPI _DSD table and take benefit of DSM on RT1011. The kernel driver device properties of RT1011 are documented at linux/Documentation/devicetree/bindings/sound/rt1011.txt It is currently in ASoC maintainer's tree at https://kernel.googlesource.com/pub/scm/linux/kernel/git/broonie/sound/+/for-next/ and hopefully should be merged to mainline kernel in the next merge window. BUG=b:140397934 BRANCH=none TEST=On Helios, with patch series, check realtek,r0_calib and realtek,temperature_calib are available to rt1011 codec driver.

If there was no match, util/sconfig would currently choose to use the empty weak declaration it creates in static.c file.

2019-09-02drivers/vpd: add framework to search VPD in romstageJonathan Zhang
Summary: Added a framework to search VPD in romstage before memory is avilable. vpd_cbmem.c and vpd_premem.c are added for code specific for premem environment and for environment that cbmem can be used. Since global variable is forbidden in romstage. A CAR_GLOBAL variable is defined in vpd.c. This variable holds VPD binary blobs' base address and size from memory mapped flash. The overall flow is: * The CAR variable g_vpd_blob is initialized if it was not, either at romstage (before FSP-M execution in case of FSP UPD customization), or at ramstage. * At ramstage, during CBMEM_INIT, the VPD binary blob contents are copied into CBMEM. * At vpd_find() which may be called at romstage or at ramstage, it sets storage for a local struct vpd_blob variable. * The variable gets contents duplicated from g_vpd_blob, if vpd_find() is called at romstage. * The variable gets contents obtained from CBMEM, if vpd_find() is called at ramstage. Added a call vpd_get_bool(). Given a key/value pair in VPD binary blob, and name of a bool type variable, set the variable value if there is a match. Several checks are in place: * The key/value length needs to be correct. * The key name needs to match. * THe value is either '1' or '0'. Test Plan: * Build an OCP MonoLake coreboot image, flash and run.

2019-08-20src: Remove variable length arraysJacob Garber
Variable length arrays were a feature added in C99 that allows the length of an array to be determined at runtime. Eg. int sum(size_t n) { int arr[n]; ... } This adds a small amount of runtime overhead, but is also very dangerous, since it allows use of an unlimited amount of stack memory, potentially leading to stack overflow. This is only worsened in coreboot, which often has very little stack space to begin with. Citing concerns like this, all instances of VLA's were recently removed from the Linux kernel. In the immortal words of Linus Torvalds [0], AND USING VLA'S IS ACTIVELY STUPID! It generates much more code, and much _slower_ code (and more fragile code), than just using a fixed key size would have done. [...] Anyway, some of these are definitely easy to just fix, and using VLA's is actively bad not just for security worries, but simply because VLA's are a really horribly bad idea in general in the kernel. This patch follows suit and zaps all VLA's in coreboot. Some of the existing VLA's are accidental ones, and all but one can be replaced with small fixed-size buffers. The single tricky exception is in the SPI controller interface, which will require a rewrite of old drivers to remove [1].
