I tried the above steps to compile vexpress_aemv8a, but i get the following
errors. Any idea?

aarch64-linux-gnu-gcc: error: unrecognized command line option '-marm'
aarch64-linux-gnu-gcc: error: unrecognized command line option
'-mno-thumb-interwork'
aarch64-linux-gnu-gcc: error: unrecognized command line option
'-mabi=aapcs-linux'
aarch64-linux-gnu-gcc: error: unrecognized command line option
'-mword-relocations'

my u-boot points to "22a240c serial/serial_arc - add driver for ARC UART".

Thanks,
Inder
