Anton Blanchard 1fa0b332ca micropython only requires 512kB of BRAM 
Mikey points out that our stack grows down from 512kB and our
heap is below that too, so we can reduce our BRAM requirements,
which allowing some smaller FPGA boards to work. Not sure why
I thought we were using memory between 512kB and 1MB.

Olof Kindgren b9bf19f912 Added synthesis target 
The synth target can be used to analyze the core after synthesis
without running P&R. Currently, the only edalize backends that
support synthesis without P&R are vivado and icestorm, and icestorm
needs yosys built with verific support to parse vhdl.

To run synthesis only for a part, run

fusesoc run --target=synth --tool=vivado microwatt --part=<part>

where part is a valid Xilinx part such as xc7a100tcsg324-1

Anton Blanchard 37fe8b954c Add a few more FPGA related files 
Add a temporary gcc patch to remove hardware divide instructions.

Also add a firmware.hex file built with a gcc with the above patch.

Right now micropython assumes 1MB of BRAM, which limits the FPGAs
we can run on. We should be able to cut it down somewhat.
