These patches are to add dependencies of POWER_RESET for MIPS Malta, x86, and PowerMac. I am really sorry I forget to use --thread in v1[1] as I stayed up too late. So here I am resending v2 patch with a mirror fix and consolidating them into a thread. To simplify the enablement of the poweroff support, selecting the required options for CONFIG_POWER_RESET=y may make many people happy especially when they are using a customized config (maybe tinyconfig based) for a target qemu board. Without normal poweroff support from the kernel side, qemu will simply hang[2] there after a 'poweroff' command, which is a very bad experience for the automatical tests. Currently, based on tinyconfig, it is very hard to find the exact poweroff options[3]. Some architectures' poweroff works well without any dependence, the others' poweroff options are hidden deeply, which make things hard. After multiple verifications, these options have been identified as the minimum dependencies required for poweroff to function normally. Zhangjin and I invested a significant amount of time in searching for the current options on these devices. We hope that this set of patches will save time for others. If community like it, we will consider adding dependencies for POWER_RESET on other devices. --- [1]: https://lore.kernel.org/lkml/20230831201727.3177853-1-tanyuan@xxxxxxxxxxx/ [2]: https://lore.kernel.org/lkml/511b2f6009fb830b3f32b4be3dca99596c684fa3.1689759351.git.falcon@xxxxxxxxxxx/ [3]: https://lore.kernel.org/all/983843582e52e83fba79ad45cea6c79e1f62ec6c.1690489039.git.falcon@xxxxxxxxxxx/ --- Changes since v1: - Fix the mistake of using spaces instead of tabs in kconfig.
