On MP1 SoC, RNB signal (NAND controller signal) and NWAIT signal (PSRAM controller signal) have been integrated together in the SoC. That means that the NAND controller and the PSRAM controller (if the signal is used) can not be used at the same time. On MP25 SoC, the 2 signals can be used outside the SoC, so there is no more restrictions.
MP1 SoC also embeds revision 1.1 of the FMC2 IP when MP25 SoC embeds revision 2.0 of the FMC2 IP.
