    Abstract: In an example, a system-on-chip (SoC) includes a hardware power-on- reset (POR) sequencer circuit (142) coupled to a POR pin (135). The SoC further includes a platform management unit (PMU) (122), coupled to the hardware POR sequencer circuit, the PMU including one or more central processing units (CPUs) (304) and a read only memory (ROM) (312). The SoC further includes one or more processing units (116, 118, 120) configured to execute a boot process. The hardware POR sequencer circuit is configured to initialize the PMU. The one or more CPUs of the PMU are configured to execute code (334) stored in the ROM to perform a pre-boot initialization.

    Abstract: In one example of the present disclosure, a computing system is provided. The computing system is to initiate a power on self-test (POST) process, determine that a change has been made to system firmware configuration data, start a timer, and determine that the timer has expired. Thereafter, the computing system is to power-off and power-on the computing system, replace current system firmware configuration data with backup system firmware configuration data, and/or generate a notification indicating system firmware configuration data has been reverted.

    Abstract translation: 在本公开的一个示例中,提供了一种计算系统。 计算系统是启动电源自检(POST)过程,确定已对系统固件配置数据进行更改,启动定时器,并确定定时器已过期。 此后,计算系统将关闭并打开计算系统,将备用系统固件配置数据替换为当前系统固件配置数据,和/或生成指示系统固件配置数据已恢复的通知。
