In base-hw/src/core/include/spec/imx53/trustzone/csu.h, SECURE   = 0x33.

So SECURE_UART  = 1 in
base-hw/src/core/include/spec/imx53_qsb/trustzone/csu_config.h should
initialize UART as RD+WR for secure user and spvr models as given in Page
956 of http://www.nxp.com/docs/en/reference-manual/iMX53RM.pdf.

tz_vmm is in the secure user mode, sho it should be able to read an UART
