This event code represents the firmware source to use at boot. Value 0 means using "standard" firmware source, value 1 means using "alternative" firmware source.
For example, some hardware has the ability to force the BOOTROM to load the bootloader from a secondary firmware source (say SD card) instead of trying with the standard first and then the secondary. This event allows the userspace to know which firmware source was requested *in hardware*.
