Is your DTS entry includes for serial node following entries: reg-io-width = <4> native-endian; if answer is yes you should expect (in case of big endian compilation) that: port->iotype would be equal to UPIO_MEM32BE, hence no readl() use for this case. This is how it works for me here, it sounds like your case is similar.
