AMBA AHB5 to AHB lite

AHB-lite, or "AMBA 3 AHB-lite" to use its more formal name, is a predecessor to "AMBA 5 AHB", or AHB5 as you call it, so the protocol evolution is "AHB-lite" to "AHB5" instead of the direction you asked about.

"AHB5" adds extra functionality and clarifications of a few common functions compared to "AHB-lite", so  if you look at the back of the "AHB5" protocol document (Appendix A) you will see a list of changes in the current protocol document compared to the earlier "AHB-lite".

The main changes are additional HPROT bits to signal more memory types, support for security signalling and support for exclusive transfers.
