So looks like similar to other macros, UART_FCR_EM (0x3) is sensible one.

UART_FCR_RO_OFFSET (9)
UART_FCR_RO_EM (UART_FCR_EM + UART_FCR_RO_OFFSET)


static unsigned int serial8250_em_serial_in(struct uart_port *p, int offset)
case UART_FCR_RO_EM:
	return readl(p->membase + (offset - UART_FCR_RO_OFFSET << 2));



Please send a complete patch as a reply. I am completely lost now.
