Joel Stanley	621da8106f	antmicro-artix-dc-scm: Add SPI flash pins Signed-off-by: Joel Stanley <joel@jms.id.au>	2 years ago
Joel Stanley	fdc44a71a0	antmicro-artix-dc-scm: Update DRAM properties Most pins are set to SSTL15, but litex generates SSTL135. This should silence a vivado warning. Signed-off-by: Joel Stanley <joel@jms.id.au>	2 years ago
Paul Mackerras	9b184ff569	antmicro-artix-dc-scm: Add DRAM support This uses the exact same gateware as the nexys video, since the DRAM connection is identical to the nexys video down to the pin assignments on the FPGA. The only minor difference is that the DRAM chip on the dc-scm is a MT41K256M16TW vs. a ...HA part on the nexys video.
