Here you go. Start at the wget.

Angel semihosting isn't implemented upstream so a text hello world won't be
trivial, although given enough time it should be possible to implement Angel
semihosting for A64 in QEMU, implement DCC in QEMU and Newlib/libgloss or
implement PL011 UART or VirtIO-MMIO console in Newlib/libgloss.
Some of the bootloaders and firmwares out there (bootwrapper, ARM trusted
firmware, UEFI/Tianocore) may have examples of using the PL011 UART.
