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.

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.

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.

There are two hard things in computer science: cache invalidation, naming things, and off-by-one errors. -- Anonymous var_num records the number of initialized entries in the reg_var array. However, this means the index of the last initialized element is one less than the value of var_num, so we need to take that into account when indexing into the array.

2019-06-21sb/amd/sr5650: Use 32 bit integers when disabling portsJacob Garber
This function attempts to set bits in the 20s of state and state_save, which won't work since those variables are only 16 bits wide. Extend them to 32 bits to capture all the bit operations.

2019-06-20southbridge/intel/common/smbus: Add do_i2c_block_write()Frans Hendriks
Intel Braswell supports i2c block writes using SMBus controller. This support is missing in actual smbus routines. Add do_i2c_block_write() which is a based on do_smbus_block_write() but also write first byte to SMBHSTDAT1. The caller needs to configure the SMBus controller in i2c mode. In i2c mode SMBus controller will send the next sequence: SMBXINTADD, SMBHSTDAT1, SMBBLKDAT ..
