Hi Peter,
I was able to progress well using the BE8 work in the branch that you pointed out. I am experiencing floating point issue. The qemu just exits, by putting a message that "floating point exception(core dumped)". I suppose QEMU do support floating point operations. I heard about hard floating point and soft floating point support. Is there any configuration option in QEMU for floating point? 

ThanksSridhar

The latest work is here, which should handle be8 and AA64 big endianness:
