MiSoC - a high performance and small footprint SoC based on Migen.
This program builds and/or loads MiSoC components.
One or several actions can be specified:
clean delete previous build(s).
build-bitstream build FPGA bitstream. Implies build-bios on targets with
integrated BIOS.
build-headers build software header files with CPU/CSR/IRQ/SDRAM_PHY definitions.
build-csr-csv save CSR map into CSV file.
build-bios build BIOS. Implies build-header.
load-bitstream load bitstream into volatile storage.
flash-bitstream load bitstream into non-volatile storage.
flash-bios load BIOS into non-volatile storage.
all clean, build-bitstream, build-bios, flash-bitstream, flash-bios.
Load/flash actions use the existing outputs, and do not trigger new builds.
