An extra uart is added at 0xc0008000 attached to valentyusb, using the OrangeCrab's onboard USB port. This has a liteuart interface, an identifier bit is added to syscon. Generated from branch hw_cdc_eptri of https://github.com/litex-hub/valentyusb The generate script is based on valentyusb/sim/generate_verilog.py UARTUSB: usbserial@8000 { device_type = "serial"; compatible = "litex,liteuart"; reg = <0x8000 0x100>; interrupts = <0x15 0x1>; }; (requires extra kernel patches for early console at present v5.16) Signed-off-by: Matt Johnston <matt@codeconstruct.com.au>
usb_hello is a copy of hello_world but uses both consoles Signed-off-by: Matt Johnston <matt@codeconstruct.com.au>
That makes it easier to override a non-litedram build for testing RAM_INIT_FILE, eg make microwatt.dfu LITEDRAM_GHDL_ARG=-gUSE_LITEDRAM=false RAM_INIT_FILE=usb_hello/usb_hello.hex Signed-off-by: Matt Johnston <matt@codeconstruct.com.au>
I added a simple 3D maze game that is a pretty impressive demo of what Microwatt can do. It's based on antonblanchard#347 Signed-off-by: Jacob Lifshay <programmerjake@gmail.com>

log2ceil() returns the number of bits required to store a value, so we need to pass in memory_size-1, not memory_size. Every other user of log2ceil() gets this right. Signed-off-by: Anton Blanchard <anton@linux.ibm.com>
wishbone_bram_wrapper ram_addr_bits is 1 bit off
This allows us to boot from flash for example. Signed-off-by: Anton Blanchard <anton@linux.ibm.com>
