- Updated filelist to include new XPI source files. - Modified IRQ compatibility mapping for XPI in the SOC topology generator. - Adjusted JSON topology configuration to reflect new IRQ signal naming. - Changed software.mk to reference the new XPI HAL source file. - Enhanced APB4 peripheral module to include XPI IRQ signal. - Updated RTL style audit to include new XPI files. - Documented new XPI programming script in README. - Added a new script for programming XPI flash through OpenOCD. - Enhanced XPI IO testbench to validate new LUT engine and isolation behavior. - Created unit tests for the new XPI programming tool and its functionalities.
