🦋 DESCRIPTION 🦋

okay so here’s the tea: this function converts a base address of lbc into the right format for the BR register. 🫶

if the SOC has eLBC, then it returns a 32bit physical address. else, it converts a 34bit local bus physical address to the correct format of a 32bit address for the BR register. example: MPC8641. that’s it, that’s the whole vibe. ✨
