2019-11-14cbfs: Stop checking master headerJulius Werner
The CBFS master header is a legacy structure that just conveys the same information we already have from the FMAP these days. We're still including it to support older CBFS implementations in some payloads, but there's no need for coreboot itself to follow this indirection anymore. This patch simplifies the default CBFS locator to just return the CBFS offset and size from the FMAP directly.

2019-08-20vc/amd/cimx/sb800: Remove old strict-aliasing workaroundJacob Garber
C strict aliasing rules state that it is undefined behaviour to access any pointer using another pointer of a different type (with several small exceptions). Eg. uint64_t x = 3; uint16_t y = *((uint16_t *)&x); // undefined behaviour From an architectural point of view there is often nothing wrong with pointer aliasing - the problem is that since it is undefined behaviour, the compiler will often use this as a cop-out to perform unintended or unsafe optimizations. The "safe" way to perfom the above assignment is to cast the pointers to a uint8_t * first (which is allowed to alias anything), and then work on a byte level: *((uint8_t *)&y) = *((uint8_t *)&x); *((uint8_t *)&y + 1) = *((uint8_t *)&x + 1); Horribly ugly, but there you go. Anyway, in an attempt to follow these strict aliasing rules, the ReadMEM() function in SB800 does the above operation when reading a uint16_t. While perfectly fine, however, it doesn't have to - all calls to ReadMEM() that read a uint16_t are passed a uint16_t pointer, so there are no strict aliasing violations to worry about (the WriteMEM() function is exactly similar). The problem is that using this unnecessary workaround generates almost 50 false positive warnings in Coverity. Rather than manually ignore them one-by-one, let's just remove the workaround entirely. As a side note, this change makes ReadMEM() and WriteMEM() now match their definitions in the SB900 code.

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].

The bdk_phys_to_ptr() function converts a uint64_t address to a void * pointer. Judging by the comments, the old implementation had a check that would refuse to convert a null pointer, which required several workarounds when trying to convert the address 0 to a pointer. This isn't the case for coreboot though, which implements this function as a simple (void *) cast, so we can remove the old workarounds.
