- Introduced a new testbench for the SDIO wrapper () to validate APB interactions. - Updated to include IRQ handling for SDIO0 and SDIO1. - Enhanced to account for performance management of SDIO0 and SDIO1. - Modified memory map tests to include SDIO base addresses and performance wait offsets. - Updated pin mapping tests to include SDIO1 signals. - Created a comprehensive suite of SDIO tests () covering various functionalities including CRC, command engine, DMA, and standalone operations. - Added a new test for verifying SDIO register parity against the RTL definition. - Adjusted SOC topology tests to reflect the addition of SDIO in the IRQ and APB fabric.
