2024-01-31include/device/device.h: Remove CHIP_NAME() macroNicholas Sudsgaard
Macros can be confusing on their own; hiding commas make things worse. This can sometimes be downright misleading. A "good" example would be the code in soc/intel/xeon_sp/spr/chip.c: CHIP_NAME("Intel SapphireRapids-SP").enable_dev = chip_enable_dev, This appears as CHIP_NAME() being some struct when in fact these are defining 2 separate members of the same struct. It was decided to remove this macro altogether, as it does not do anything special and incurs a maintenance burden.

2024-01-24soc/*: Rename Makefiles from .inc to .mkMartin Roth
The .inc suffix is confusing to various tools as it's not specific to Makefiles. This means that editors don't recognize the files, and don't open them with highlighting and any other specific editor functionality. This issue is also seen in the release notes generation script where Makefiles get renamed before running cloc.

2022-05-02soc/mediatek/mt8186: Prevent early USB wakeupRex-BC Chen
The MT8186 platform fails to suspend due to premature wakeup by USB. In MT8186, we use low level latch to keep USB wakeup signal. However, hardware could latch a wrong signal if it debounces more than one time. As a result, it would enable wakeup function too early. To prevent this issue, we do the following modification: - Delay about 100 us to enable wakeup function in kernel drivers [1]. - To guarantee 100 us is enough, we need to disable the USB debounce by default in coreboot. According to section register 0x404 and 0x420 in "(CODA) MT8169_PERICFG_REG.xls" which is only for MediaTek internal use: The current default value of debounce register for MT8186 USB IP0 and IP1 is incorrect. The reason we add in coreboot is that the default value should be correct when SoC is booting up. This modification is only for MT8186. The subsequent SoCs will adjust the wakeup function to correct register value by default.
