Merge pull request #145 from zeldin/bigendian2 
Update big endian instruction encoding
 2020-10-21 12:56:56 +02:00
Marcus Comstedt 6c8e97f825 Update big endian instruction encoding 
Between draft-20181101-ebe1ca4 and draft-20190622-6993896 of the
RISC-V Instruction Set Manual, the wording was changed from requiring
"natural endianness" of instruction parcels to require them to be
little endian.

Update the big endian instruction pipe to reflect the newer requirement.
