XDP - Xilinx Drone Platform is a board for drones or other UAV. Pinmux the SD card by default, and if the SD card detect line is high (inactive) then pinmux the SD1 interface to EMIO instead. SD is placed on extension card and shares connection with on board wife. That means that when SD card is present in the board wifi can't be used. There seems to be an issue with DDR access from PL at 2400MT/s, after updating the PMU and ATF firmware this is causing extremely slow DDR access. Reducing the DDR speed from 2400 to 2133 appears to solve that issue, even though the hardware has proven to be 2400 capable.
