BBAI power control of external resources

BBAI SRM ------------ 6.1.1 TPS6590379 PMIC

One dedicated pin in each package can be configured as part of the power-up sequence to control external resources. General-purpose input-output (GPIO) functionality is available and two GPIOs can be configured as part of the power-up sequence to control external resources.

does anyone have more info on this?

also, what is a ‘package’ in this context?
