You're right about the commit message: I saw the LED lit before Linux probes and assumed the firmware set it, without checking where it comes from. On the Lite, the schematic (sheet 21) shows RGPIO3 driving the system LED and also used for fastboot detection, through jumper J20 that pulls it to 1.8 V via R257 (1k). Detection happens at reset, before Linux, and R257 limits the current whichever level the pin is driven to afterwards, so I don't think driving it high conflicts there. Owen
