In principle, yes. Documentation/debug-output.md tells you how: JAILHOUSE_CON_TYPE_8250, JAILHOUSE_CON_ACCESS_MMIO, and you may have to try both JAILHOUSE_CON_REGDIST_1 and JAILHOUSE_CON_REGDIST_4 to see which one is needed. Only if the UART requires some magic enabling dance via other resources, this would not work.
