This patch series provides an implementation of Nuclei FPGA Machine[1]. At present, only MCU mode support is included. In mcu mode, We will use eclic[2] as interrupt controller. It is compatible with clic in Machine mode. But It contains some customized csr[3] that will take up part of the csr code. If there is any question, please let me know.
Features: 1.Add Nuclei CSR support in eclic mode 2.Add ECLIC Device 3.Add Systimer Device 4.Add Uart Device 5.Add Nuclei FPGA Machine It have passed Nuclei SDK[4](not include dsp) and RTThread[5] HBird BSP Test.
