This target has full device tree support, thus reducing the number of patches needed for bcm63xx, in which there's a patch for every board. The intention is to start with a minimal amount of downstream patches and start upstreaming all of them. Current status: - Enabling EHCI/OHCI on BCM6358 causes a kernel panic. - BCM63268 lacks Timer Clocks/Reset support. - No PCI/PCIe drivers. - No ethernet drivers.
