Contributions summary:Andreas primarily contributed to the development of an IRQ-driven SPI data transfer mechanism within the NEORV32 RISC-V soft-core CPU project. Their work involved introducing and refining functions for SPI interrupt service routines, and the implementation of a data transfer framework including the utilization of FIFO buffers. They also made modifications to the `neorv32_spi.c` and `neorv32_spi.h` files to integrate ISR based data flow and fix various related bugs.
