Comment:
The limit of 4 "legacy" serial ports is archaic and really no longer applies to modern 64 bit systems. Kernel config entries CONFIG_SERIAL_8250_NR_UARTS=48 and
CONFIG_SERIAL_8250_RUNTIME_UARTS=32 is what is used for Ubuntu. The user can change the limit of available RUNTIME serial ports with the 8250.nr_uarts=x kernel variable. nr_uarts cannot be more than the max set with CONFIG_SERIAL_8250_NR_UARTS.
