Interface stabilization

This release stabilizes the IOb native interface to connect the processor to the peripherals. The semantic is close to the AXI Lite handshake protocol, where the valid signal must not depend on the ready signal, and the ready signal may or may not depend on the valid signal. The registration of outputs is now mandatory. Consecutive reads or writes are possible, enabling pipelining. However, since the valid and r_ready_ signals are used both for reading and writing, and the ready output on the slave must be registered, changing from reads to writes or vice-versa needs a dead cycle in between. Many hardware modules have been improved or added; the iob_timer peripheral and the truly asymmetric iob_bfifo components are highlighted. The mkregs.py script that automatically inserts control and status registers in peripherals has been upgraded to support external IOb, AXI Lite, or AMBA APB interfaces. The suffixes _i and _o have been added to many module IOs to improve readability but may need to be added in some modules.

Python Automation

This release introduces Python scripts to automate the creation of a build directory with all the necessary files and build makefiles for running emulation, RTL simulation, and FPGA. There are also significant advances in the automatic creation of Control and Status Register (CSR) files, comprising both the hardware and bare-metal software and in generating standard interfaces such as AXI4 and AMBA. The UART and LIB submodules have been integrated into IOb-SoC, which reduces the use of git submodules and associated problems.
