2024-03-15treewide: Move stdlib.h to commonlibMaximilian Brune
This patch moves commonlib/stdlib.h -> commonlib/bsd/stdlib.h, since all code is BSD licensed anyway. It also moves some code from libpayloads stdlib.h to commonlib/bsd/stdlib.h so that it can be shared with coreboot. This is useful for a subsequent commit that adds devicetree.c into commonlib. Also we don't support DMA on arm platforms in coreboot (only libpayload) therefore `dma_malloc()` has been removed and `dma_coherent()` has been moved to architecture specific functions. Any architecture that tries to use `dma_coherent()` now will get a compile time error. In order to not break current platforms like mb/google/herobrine which make use of the commonlib/storage/sdhci.c controller which in turn uses `dma_coherent` a stub has been added to arch/arm64/dma.c.

2022-08-01include: Add SPDX-License-Identifiers to files missing themMartin Roth
This adds SPDX-License-Identifiers to all of the files in src/include that are missing them or have unrecognized identifiers. Files that were written specifically for coreboot and don't have license information are licensed GPL-2.0-only, which is the license for the overall coreboot project. Files that were sourced from Linux are similarly GPL-2.0-only. The cpu/power files were committed with source that was licensed as GPL-2.0-or-later, so presumably that's the license for that entire commit. The final file, vbe.h gives a pointer to the BSD-2-Clause license at opensource.org.

2015-09-22coreboot: introduce commonlibAaron Durbin
Instead of reaching into src/include and re-writing code allow for cleaner code sharing within coreboot and its utilities. The additional thing needed at this point is for the utilities to provide a printk() declaration within a <console/console.h> file. That way code which uses printk() can than be mapped properly to verbosity of utility parameters.

2014-12-15tegra124: A couple clock fixes.Gabe Black
This fixes two problems with the clock configuration on tegra124. First, the macro which set up the i2c clocks tried to account for the fact that the i2c divisor's lsb represents 1.0 where it normally represents 0.5 by multiplying the target frequency by 2. That doesn't work, unfortunately, because the divisor is actually n + 1, and what n + 1 means depends on where the one's place is in the divisor. Also, when calculating the divisor, the standard C division operator uses truncation to deal any remainder which tends to make the divisor smaller. That has the effect of making the output frequency higher than what was requested. Since it's usually safer to undershoot a frequency than overshoot it, this change makes those divisions round up instead. Finally, the hand tuned temporary UART clock configuration was adjusted so that it still ends up with the same divisor. Without that, very early output from the bootblock is garbled, specifically the coreboot welcome banner, build timestamp, etc. BUG=chrome-os-partner:27220 TEST=Built and booted on nyan. Used a logic analyzer to verify that the TPM i2c bus ran at 400KHz instead of 660KHz, and that the divisor was the expected value. Measured boot time with and without EFS and verified that there was no change. Spot checked the output for errors and verified that none of the bootblock output was garbled. BRANCH=None Had to add the stdlib.h from 89ed6c that hadn't been merged correctly.
