All likely to be included in 2016/03 upstream: * http://lists.denx.de/pipermail/u-boot/2016-February/245385.html To fix the uboot-tools build * 89ca1000 ARM: rpi: set fdt_high in the default environment This, to load fdt where VMSPLIT_3G kernel can reach it. * http://lists.denx.de/pipermail/u-boot/2016-February/245402.html Alike, for the ramdisk. That is the bare minimim to get the system to boot. There's a couple of known flaws and likely some unknown: * Some drivers are missing: http://elinux.org/RPi_Upstreaming * The ethernet MAC address is random. Fix headed for 4.6. * VC4 is not bound to the device tree. And the configfs interface to the overlays is not yet here. This could possibly be worked around by an userspace tool that would generate a desired dtb from fragments. * Not sure if simplefb works. It certainly does not for my DSI display. Didn't try with newer firmware or HDMI, will look into that. > With also Eric Anholt's new VC4 driver[1], that should get us closer > and closer from a fully-supportable Pi 2. > > If needed, I just received a bunch of Pi 2 (5 of them), that I'll be > happy to use to test, either within Red Hat premises, or from my > personal internet connection.
