It is importeant to consistently apply the same handling for flushing within
level 2 and level 1 cache handling. In this case now both handling use clean and invalidate.

1613a01bb0 libchip: Reduce tx interrupts 
Reduce number of packet transmitted interrupts by using the interrupt mechanism only
if we run out of DMA descriptors.
Under normal conditions regaining DMA descriptors, mbufs and clusters is handled
via a counter.

The baud rate of the altera cyclone-V U-Boot can not be changed at the
u-Boot console prompt. Thus we use the same baud rate as the U-Boot for
the BSP.

c5831a3f9a score: Add clustered/partitioned scheduling 
Clustered/partitioned scheduling helps to control the worst-case
latencies in the system.  The goal is to reduce the amount of shared
state in the system and thus prevention of lock contention.  Modern
multi-processor systems tend to have several layers of data and
instruction caches.  With clustered/partitioned scheduling it is
possible to honour the cache topology of a system and thus avoid
expensive cache synchronization traffic.

We have clustered scheduling in case the set of processors of a system
is partitioned into non-empty pairwise-disjoint subsets.  These subsets
are called clusters.  Clusters with a cardinality of one are partitions.
Each cluster is owned by exactly one scheduler instance.

69aa33490b score: Simplify thread control initialization 
The thread control block contains fields that point to application
configuration dependent memory areas, like the scheduler information,
the API control blocks, the user extension context table, the RTEMS
notepads and the Newlib re-entrancy support.  Account for these areas in
the configuration and avoid extra workspace allocations for these areas.

This helps also to avoid heap fragementation and reduces the per thread
memory due to a reduced heap allocation overhead.

e1598a616d score: Static scheduler configuration 
Do not allocate the scheduler control structures from the workspace.
This is a preparation step for configuration of clustered/partitioned
schedulers on SMP.
