We use a #define on guybrush to make it easier to understand: https://review.coreboot.org/plugins/gitiles/coreboot/+/refs/heads/master/src...

Normally you can pick any GEVENT as long as it's not used. GEVENTs 0-23(?) can be mapped to GPIOs if desired, 24-31 are internal only GEVENTs. So we generally use 24+. For xhci we use 31: https://review.coreboot.org/plugins/gitiles/coreboot/+/refs/heads/master/src...
