2019-12-02src/: Remove g_ prefixes and _g suffixes from variablesPatrick Georgi
These were often used to distinguish CAR_GLOBAL variables that weren't directly usable. Since we're getting rid of this special case, also get rid of the marker. This change was created using coccinelle and the following script: @match@ type T; identifier old =~ "^(g_.*|.*_g)$"; @@ old @script:python global_marker@ old << match.old; new; @@ new = old if old[0:2] == "g_": new = new[2:] if new[-2:] == "_g": new = new[:-2] coccinelle.new = new @@ identifier match.old, global_marker.new; @@ - old + new @@ type T; identifier match.old, global_marker.new; @@ - T old; + T new; @@ type T; identifier match.old, global_marker.new; @@ - T old + T new = ...; There were some manual fixups: Some code still uses the global/local variable naming scheme, so keep g_* there, and some variable names weren't completely rewritten.

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.

2019-06-18sb/intel/spi: Check for the SPI lock bit during runtimeArthur Heymans
The SPI swseq controller can be locked in other parts of the code, for instance when it's locked down in the finalize section. The driver has to be made aware of that. The simpler solution is to not keep track of the state and simply read out the lock bit on each SPI transfer.

2019-04-21nb/intel/haswell: Add an option for where verstage startsArthur Heymans
Previously Haswell used a romcc bootblock and starting verstage in romstage was madatory but with C_ENVIRONMENT_BOOTBLOCK it is also possible to have a separate verstage. This selects using a separate verstage by default but still keeps the option around to use verstage in romstage. Also make sure mrc.bin is only added to the COREBOOT fmap region as it requires to be run at a specific offset. This means that coreboot will have to jump from a RW region to the RO region for that binary and back to that RW region after that binary is done initializing the memory.
