Trying to make de0_nano boot from spi flash.
I am using fusesoc. Bootrom taken from orposc v2.
Added #define BOOTROM_SPI_FLASH to bootrom.S form orpsoc v2
Modified bin2vlogarray to this
https://drive.google.com/file/d/0B5U7b-LVTCGtR0Z6VGlWdUxIRDA/view?usp=sharing
to create bootrom files as in orpsoc v3.
u-boot: objcopy -> bin2binsizeword -> quartus_cpf
linux: gzip -> mkimage -> bin2hex.py -> quartus_cpf
As in snippet from http://science.raphael.poss.name/intro-openrisc.html
orpsoc.cof from here: http://oompa.chokladfabriken.org/tmp/orpsoc.cof
It did not work.
