It's a regular UART - it appears as /dev/ttyAMA10, and by default /dev/serial0 is a symlink to it. You do need to be aware that the EEPROM will output diagnostics to it during boot that cannot be disabled, but you can prevent a login console being created there by removing "console=serial0,115200" from cmdline.txt.
