2019-10-03southbridge/intel: Add config option to validate firmware descriptorMathew King
Add new config option to validate the Intel firmware descriptor against the fmap layout. This will prevent a firmware descriptor from being used that could corrupt regions of the bootimage in certian circumstances.

2019-10-03sb/intel/i82801gx: Use symbolic name for register, code reworkPetr Cvek
An original code had a wrong register address 0x27 for AHCI BAR. The value was aligned incidentally by the code specific of the pci_read_config32 function to the correct address 0x24. All 0x24 values in sata.c were changed to the symbolic name PCI_BASE_ADDRESS_5 and the code was optimized. An equivalent code was tested on a real hardware.

2019-08-20nb/amd/pi,sb/amd/sr5650: Remove unnecessary allocationJacob Garber
add_ivrs_device_entries() is a recursive function, and each recursive call is passed a pointer to a root_level variable declared outside the function. In an attempt to make the function self-contained, the initial call is made with the root_level pointer set to NULL, and then the function attempts to detect this and allocate a root_level variable for the rest of the calls. This makes memory management very tricky - for example, the pi code incorrectly attempts to free the root_level variable at the end of *each* recursive call, which only avoids being a double-free because free() in coreboot is currently a no-op. Let's keep life simple and declare root_level as a local variable outside the first function call instead.

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.

2019-07-19sb/intel/{bd82x6x|ibexpeak}: Drop p_cnt_throttling_supportedPatrick Rudolph
The processor P_BLK doesn't support throttling. This behaviour could be emulated with SMM, but instead just update the FADT to indicate no support for legacy I/O based throttling using P_CNT. We have _PTC defined in SSDT, which should be used in favour of P_CNT by ACPI aware OS, so this change has no effect on modern OS. Drop all occurences of p_cnt_throttling_supported and update autoport to not generate it any more.

2019-07-19sb/amd/sb800: Remove bit shift that does nothingJacob Garber
This bit shift attempts to set bits 8 and 9 of the byte variable (counting from 0). However, as the name suggests, this variable is only 8 bits wide, so the shift does nothing. Reading section 7.5 of the AMD SB800-Series Southbridges Register Programming Requirements manual, bits 8 and 9 are already set by default, so we can remove the bit shift. (Alternatively, we could try setting the corresponding bits one byte higher in 0xF1 if needed.)

2019-07-19src: Make implicit fall throughs explicitJacob Garber
Implicit fall throughs are a perpetual source of bugs and Coverity Scan issues, so let's squash them once and for all. GCC can flag implicit fall throughs using the -Wimplicit-fallthrough warning, and this should ensure no more enter the code base. However, many fall throughs are intentional, and we can use the following comment style to have GCC suppress the warning. switch (x) { case 1: y += 1; /* fall through */ case 2: y += 2; /* fall through - but this time with an explanation */ default: y += 3; } This patch adds comments for all remaining intentional fall throughs, and tweaks some existing fall through comments to fit the syntax that GCC expects.

2019-07-17sb/amd/sr5650: Add fine-grained bounds checkingJacob Garber
The code currently checks that 4 <= dev_index <= 10, which after subtraction by 4 can index into an array of length at most 7. This is fine for the largest cpl array (which does have length 7), but is too large for some of the others, which are smaller. This adds bounds checks for each array access to ensure they are all within bounds.
