LiteX SoC build for MAX1000

[Antti Lukats]

Hi,

LiteX SoC with default VexRiscv RISC-C core is still much WiP but already booting LiteX BIOS and having SDRAM memtest OK on MAX1000

LiteX --->

link to litex-boards fork with MAX1000 support

Base SoC seems working, 8 LED's connected to GPIO, SPI Flash and user connectors, etc, not connected to anything.

Note 1: setting up LiteX may be a struggle, it is possible even on windows but the linux bootstrap is recommended way.

Note 2: LiteX has an open bug report - currently the generated ROM will be implemented as LUTROM on MAX10, so I had to manually patch the generated .v file, this will be fixed in LiteX, well hopefully
