DE2-115 Development board, What IP to select in Qsys for NOR flash controller

I am trying to port u-boot into DE2-115 board. Am using Quartus-II 14.0/Qsys. I want to use the NOR flash in the DE2-115 board.

altera_avlon_cf in Qsys doest support NOR flash. Any other option?

    What NOR FLASH are you referring to?

    Are you looking to use the SD card in some way? You can use the "SPI (3 Wire Serial)" Qsys peripheral to access that as a starting point.

    Cheers,

    You will need to use the tri-state bridge and cfi memory controller. There are several examples of this on the DE2-115 system CD. I've seen a video demonstration as well, but I don't recall the title. I don't remember if the cfi flash can be used to store the FPGA configuration or only software for the embedded NIOS.
