Are there commodity ARM SOCs with built-in PCIe controller logic? Or is the idea that you have a separate controller chip? Is PCIe used in ARM systems or do they use a different bus - axi??? Sorry for the dumb questions. Hardware hobbyist here :)

Yes, many ARM based SOCs include PCIE IP...SOCs from Freescale, TI, Nvidia, etc. typically supporting PCIE RC and EP.

Lots of boards with ARM based SOCs are using PCIE WiFi/BT combo chips which traditionally used SDIO. PCIE also being used for storage.
