QSPI_IND_AHB_ADDR_TRIGGER : Trigger Address is the base address that is used by the AHB controller for indirect accesses. When the incoming AHB access address matches a range of addresses from this trigger address to the trigger address + 15, then the AHB request is completed by fetching/storing data from/to the Controllers SRAM.

By Masking with 0xF_FFFF, the value to be loaded in the indirect trigger register becomes zero & then spi read/write does not work. By removing or changing the mask to 0xFFFF_FFFF, the loaded value in indirect trigger register is 0x4000_0000 & spi read/write works fine. It should be same of socfpga also after masking with 0xF_FFFF, wondering how it works there. No masking is done in the driver while polling fifo for read/write, plat->ahbbase was used directly.
