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. Signed-off-by: Anton Blanchard <anton@linux.ibm.com>	5 years ago

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. Signed-off-by: Anton Blanchard <anton@linux.ibm.com>	5 years ago
