Hi,

Beckhoff has build a board, called CX7200, based on the Xilinx Zynq A9
platform. This commit series adds the Beckhoff CX7200 as new board variant to
QEMU.

The emulation is able to successfully boot an CX7200 image. The image includes
some self tests executed on every boot. Only the cache self test fails due to
QEMU emulating the cache as always being coherent. The self tests include f.e.:

* Network
* Flash
* CCAT DMA + EEPROM [1]
* TwinCAT (Beckhoff's automation control software [2])
