Add the Hackaday Supercon 2019 badge which has an ECP5 FPGA: https://hackaday.io/project/167255-2019-hackaday-superconference-badge These changes are from Michael Welling's fork: https://github.com/mwelling/linux-on-litex-vexriscv During Supercon, we trying two approaches: - use the built-in 16MB QSPI SRAM - use add-on cartiridge with 32MB SDRAM by Jacob Creedon We were not able to get the QSPI SRAM working so I've removed those changes, and I have just added the changes that are needed to boot Linux with the 32MB SDRAM. Thanks to Jacob Creedon, Greg Davill and Tim Ansell who helped debug. KiCad design files for the SDRAM cartridge are available at: https://github.com/jcreedon/dram-cart/ The SDRAM cartridge PCB is shared at: https://oshpark.com/shared_projects/IQSl2lid More information in this blog post: https://blog.oshpark.com/2019/12/20/ The Hackaday Supercon badge PCB design is here: https://github.com/Spritetm/hadbadge2019_pcb

Fomu Hacker supports dual spi, so add a "spiflash4x" definition. The litex spi_flash module will run this flash in dual mode, because the `dq` array is only two signals wide. Signed-off-by: Sean Cross <sean@xobs.io>

The evt platform has a different naming scheme from the other two versions of Fomu. This harmonises the naming of the rgb_led pads between all of the Fomu variants. Signed-off-by: Sean Cross <sean@xobs.io>
