The huge majority of the armhf/arm64 cards being put to work today do not have a pci slot and never will, yet there are 100 of these tiny sbc's out here doing real work that will never do it thru a pci or pci-e connector. Today, on arm stuff, that interface is SPI, and it runs at speeds up to 50 megabaud on the r-pi-3b. Give us a kernel installer that Just Works using a kernel we've downloaded the src for and built right on these teeny boards, and give us a 50 megabaud SPI driver, support the mali video chips these things come with, and a huge bunch of these little cards will be off to the races. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
