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].

IMC is found on certain Xeon processors. On such platforms SPDs are not connected to SMBus on PCH but to dedicated IMC-owned pins. The purpose of this driver is to expose access to the i2c/smbus controller associated with IMC. Datasheet used: Intel Xeon Processor D-1500 Product Family, Volume 2, reference 332051-001 This driver is largely based on i2c-imc.c Linux driver. https://lwn.net/Articles/685475/ TEST=single/double reads and single writes on Xeon-D1500.

2019-08-13soc/intel/fsp_broadwell_de: Enable early integrated UARTAndrey Petrov
In order to use internal UART it needs to 'enabled'. This is normally done by FSP. However sometimes internal UART is needed before FSP is invoked. TEST=check if printk() show up in early romstage. Tested on OCP Monolake. Tested on out-of-tree mainboard to see if UART on LPC still works.

2019-08-13soc/mediatek: dsi: Refactor MIPI TX configurationHung-Te Lin
The only platform-specific difference in mtk_dsi_phy_clk_setting is how to configure MIPI TX because those registers (and logic) are quite different across different SOCs. The calculation of data rate is actually the same so we should isolate it and move to common, and rename mtk_dsi_phy_clk_setting to a better name as mtk_dsi_configure_mipi_tx.

Change the stoneyridge definitions into picasso. The named 0 and 1 buses are controlled by the PSP and not directly accessible by host firmware. I2C4 operates only in slave mode so is not added to to the bus clear-after-reset sequence. The I2C controller is fundamentally the same as on Stoney Ridge so the ability to clear a potentially jammed bus is still required.
