af3dc4a7ca sys/arm: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

8c2df90ac9 Simplify the receiver code a bit.
Drain the RX FIFO and continue on failure.

74ccc02b18 Add the necessary support to use both TX queues available on if_emac.
Each TX queue can hold one packet (yes, if_emac can send only two(!)
packets at a time).

Even with this change the very limited FIFO buffer (3 KiB for TX and 13 KiB
for RX) fill up too quick to sustain higher throughput.

For the TCP case it turns out that TX isn't the limiting factor, but the RX
side is (the FIFO fill up and starts to discard packets, so the sender has
to slow down).

0baf1f6506 Add EMAC 10/100 Ethernet controller driver for A10/A20.
It is available mostly in A10 devices like Hackberry, Marsboard,
Mele A1000, A2000, A100 HTPC, cubieboard1 and A20 device
like cubieboard2.
TX performance can be improved using both channels 0 and 1.
RX performance is poor and needs improvement with the assistance of
external DMA controller in case there is bulk TCP receiver.
