Though altera-qspi works like CFI flash, it is not CFI flash as it does 
not have CFI info. It is a separate driver to cfi_flash.c.

Both drivers and many other parallel flash drivers under the board/arch 
directories are called by common/cmd_flash.c, which is very old and 
somewhat nasty. It could be the place for common feedback. But this is 
too far and deeply involved. I wanted to touch it a month ago, made some 
patches but withdrew then.

Best regards,
Thomas
