I am trying to boot xen(debug build) on pine64 ARM64 based board but its
hangs at following position,

- UART enabled -
- CPU 00000000 booting -
- Current EL 00000008 -
- Xen starting at EL2 -
- Zero BSS -
- Setting up control registers -
- Turning on paging -
- Ready -

but when I boot dtuart=<unknown value> say duart=xyz instead of
dtuart=serial0, xen booted successfully but Dom0 crash while probing
'serial0' driver.

If I remove 'serial0' node from device tree, Dom0 boot successfully but
unable to enter input into 'hvc' console.

what could be wrong here or missing something?
