What is a Bufferable Transaction in AHB
Bufferable Transaction can be buffered. For example if a master issues a write transaction to a Slave
via a bus or a fabric, the bus/fabric may buffer the transaction and respond OK immediately.
This means that the OK response does not come from the final destination.
The bus/fabric will in turn will transfer the write command to the final destination.
Bufferable Writes can also be called posted writes. 'Posted' Writes are the ones for which the issuer gets
no response. Though in bufferable writes the Master do get a response, but its not from the final destination
Posted/non-posted are terms from the PCIe World.
A bufferable transaction is indicated by HPROT[2], when it is '1', the transaction is bufferable.
