loading RBF file to Atera Cyclone V through SPI port from Linux

I am using I.MX6 processor to configure (loading .rbf file) the altera cyclone V FPGA through the spi port, for that i am doing a while loop and for each iteration i am reading some bytes from the rbf file and sending the readed bytes through specific spi port from my processor the the spi port of the FPGA. Thei operation take a lot of time, so i am asking if there is a Linux driver that allow this operation. (all the drivers that i am foundig use PCi port or GPIOs as this one https://github.com/ntb-ch/fpga_loader/blob/master/fpga_loader.c )
