Freescale DPAA FMan

The Freescale Data Path Acceleration Architecture (DPAA) is a set
of hardware components on specific QorIQ multicore processors.
This architecture provides the infrastructure to support
simplified sharing of networking interfaces and accelerators
by multiple CPU cores and the accelerators.

One of the DPAA accelerators is the Frame Manager (FMan)
which contains a series of hardware blocks: ports, Ethernet MACs,
a multi user RAM (MURAM) and Storage Profile (SP).

This patch set introduce the FMan drivers.
Each driver configures and initializes the corresponding
FMan hardware module (described above).
The MAC driver offers support for three different
types of MACs (eTSEC, TGEC, MEMAC).

For unprivileged functions operations can be authorised by an admin
function. Extra steps are introduced to the MCDI protocol in this
situation - the initial response from the MCDI tells us that the
operation has been deferred, and we must retry when told. We then
receive an event telling us to retry.

Note that this provides only the functionality for the unprivileged
functions, not the handling of the administrative side.
