Include testbed for simulation in GHDL.
Some top level attributes required for safe build for real hardware
with asynchronous external access has to be disabled for GHDL simulation.

LX_DAD project started.
The aim of this project is to experiment with Hamamatsu
diode array based spectrophotometer. LX_CPU1 board
designed by Petr Porazil is used as base for experiment.
Board combines NXP LPC4088, Xilinx Spartan 6 FPGA
and 32 MB of SDRAM.
Included template based on PiKRON embedded projects
to allow build of sysless and other libraries.
