2019-08-20soc/intel/cnl: Add provision to configure SD controller write protect pinAamir Bohra
Cometlake FSP allows provison to configure SD controller WP pin, As some of board design might choose not to use the SD WP pin from SD card controller. This implementation adds a config that allows to enable/disable SD controller WP pin configuration from FSP.

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].

2019-08-09soc/intel/common: Implement power-failure-state handlingNico Huber
This is a consolidation of the respective feature in `soc/intel/*lake/`, including additional support for MAINBOARD_POWER_STATE_PREVIOUS. For the latter, firmware has to keep track of the `previous` state. The feature was already advertised in Kconfig long ago, but not implemented. SoC code has to call pmc_set_power_failure_state() at least once during boot and needs to implement pmc_soc_set_afterg3_en() for the actual register write.

2019-08-09soc/intel/common/gspi: Use GSPI bus id to map to the controllerKarthikeyan Ramasubramanian
Currently SPI bus id is used to map to the controller in order to set the controller state. In certain platforms SPI bus id might not be exactly the same as GSPI bus id. For example, in Intel platforms SPI bus id 0 maps to fast spi i.e. SPI going to the flash and SPI bus id 1 .. n map to GSPI bus id 0 .. n-1. Hence using SPI bus id leads to mapping to the GSPI controller that is not enabled. Use the GSPI id bus so that the right controller is set to active state.

2019-07-29soc/intel/baytrail: Prevent unintended sign extensionsJacob Garber
Consider the following assignment: u64 = s32 For positive values this is fine, but if the s32 is negative, it will be sign-extended in the conversion to a very large unsigned integer. This manifests itself in two ways in the following code: First, gpu_pipe{a,b}_port_select are defined as int, and can have the values 1 or 2. In the case when they have the value 2, the shift 2 << 30 will be a negative number, making it susceptible to the sign-extension problem above. Change these variables to something more reasonable like a uint8_t, which is unsigned. Second, in any bit shift, any variable with width less than an int will be implicitly promoted to an int before performing the bit shift. For example, the variable gpu_pipea_power_on_delay is a uint16_t, and if its highest bit is set, the shift gpu_pipea_power_on_delay << 16 will become negative, again introducing the above problem. To prevent this, cast all smaller variables to a u32 before the shift, which will prevent the implicit promotions and sign extensions.

Since this setting doesn't matter for the GPO pad, there is no need to change the default value for such pads. The patch updates PAD_CFG_GPO* macros to set trig to disable.

2019-07-21soc/intel/common: add PAD_CFG_NF_BUF_TRIG macroMaxim Polyakov
In the case there is no the circuit diagram for motherboard, the PCH/SoC GPIOs config is based on information from the inteltool dump. However, available macros from gpio_defs.h can't define the pad configuration from this dump: 0x0440: 0x0000002084000500 GPP_A8 CLKRUN# 0x0448: 0x0000102184000600 GPP_A9 CLKOUT_LPC0 0x0450: 0x0000102284000600 GPP_A10 CLKOUT_LPC1 To convert these raw DW0/DW1 register values to macros, the following parameters must be set: func - pad function, pull - termination, rst - pad reset config, trig - rx level/edge configuration, bufdis - rx/tx (in/output) buffer disable. The patch resolves the above problem by adding a new macro for the native function configuration: PAD_CFG_NF_BUF_TRIG(pad, pull, rst, func, bufdis, trig) These changes were tested on Asrock H110M-DVS motherboard [2]. It also resolves the problem of automatically creating pads configuration [3,4] [1] page 1429,Intel (R) 100 Series and Intel (R) C230 Series PCH Family Platform Controller Hub (PCH), Datasheet, Vol 2 of 2, February 2019, Document Number: 332691-003EN https://www.intel.com/content/dam/www/public/us/en/documents/ datasheets/100-series-chipset-datasheet-vol-2.pdf [2] https://review.coreboot.org/c/coreboot/+/33565 [3] https://github.com/maxpoliak/pch-pads-parser/issues/1 [4] https://github.com/maxpoliak/pch-pads-parser/commit/215d303 Change-Id: If9fe50ff9a680633db6228564345200c0e1ee3ea Signed-off-by: Maxim Polyakov <max.senia.poliak@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/34337 Reviewed-by: Furquan Shaikh <furquan@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
