2020-01-22{soc,southbridge}/*/*/acpi: Add possibility to disable S4Wim Vervoorn
Some boards don't support S3 or S4. The S4 state can't be removed from the available sleep states. Add a config item that allows removal of the S4 state from the list of available sleep states. The S4 state can be removed by selecting the item on board level. For the AMD chipsets the SSFG mask is updated to remove the S4 state.

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].

2019-07-23sb/intel/common/spi: Increase flash erase timeoutUwe Poeche
This patch provides an increased timeout (60ms -> 1s) for SPI HW-sequencing flash erase operations. Without that the erase for MRC cache writing on siemens/mc_bdx1 sometimes goes wrong because the timeout stops waiting for flash cycle completion. It was found during continuous integration. Investigation showed that the used flash type takes sporadic (e.g. 5% of the test cycles) more time for completion of erasing operation if the ambient temperature increases. The measured time values are in range of data sheet of SPI flash. 60ms is a typical value. So increasing the value is necessary. tested on siemens/bdx1; measured time values with increased ambient temperature of flash were always smaller than worst case value of 1s.

The newest and most useful incarnation was hiding in soc/intel/common/.

Also add a new `int` config MAINBOARD_POWER_FAILURE_STATE that moves the boolean to int conversion into Kconfig: 0 - S5 1 - S0 2 - previous state This patch focuses on the Kconfig code. The C code could be unified as well, e.g. starting with a common enum and safe wrapper around the get_option() call. TEST=Did what-jenkins-does with and without this commit and compared binaries. Nothing changed for the default configurations.

The common finalise code is used by bd82x6x, Lynx Point, and Ibex Peak. Lynx Point now benefits from being able to write-protect the flash chip. For Lynx Point, writing the SPI OPMENU now happens in ramstage, as done in bd82x6x. Tested on an ASRock H81M-HDS (Lynx Point). When write-protection is configured, flashrom reports all flash regions as read-only, and does not manage to alter the contents of the flash chip. Also tested on an ASUS P8H61-M LX (Cougar Point). Everything seems to work as before.
