ATMEGA/ATXMEGA softcore IP

This is a very simple to implement MEGA/XMEGA parametrised soft core IP with all the necessary IO's for a basic utilisation.

Now that the FPGA's are on an affordable price, in some cases cheaper than an bare metal microcontroller ( for example LATTICE ICE40 UltraPlus ) and in some cases an equivalent soft core of an bare metal core is faster than the bare metal core, I developed a MEGA/XMEGA parametrised soft core with additional IO IP's like PIO, UART, SPI, TWI, LCD, GFX accelerator, even an LCD to HDMI translator for boards that have HDMI output connector on them.

The repository of this core on XILINX and LATTICE platform can be downloaded from here.
