Amber ARM-compatible core

The ethmac-test loopback doesn't work on FPGA board (xilinx SP605) although it is working during simulation. The message I got in the hyperterminal is:

all done. Can't return to boot loader because used the boot mem as a packet buffer

Working on a more advanced Ethmactest progrma that will replace the rather simple code in ethmac-test.
