May be use conditional ifdef with CONFIG_SYS_SPI_BASE instead of CONFIG_ALTERA_SPI so who ever use SPI on their board will define CONFIG_SYS_SPI_BASE config. thanks!

You can have different SPI controllers enabled on the SoCFPGA, so enabling CONFIG_ALTERA_SPI explicitly in case CONFIG_SYS_SPI_BASE is defined is a very bad idea. Best regards, Marek Vasut
