I now have dCore booting on the GK802 Quad Core i.Mx6. Since this is an Arm v7 machine, it is running the base rootfs as the Allwinner.
U-boot and the boot procedure is quite different, and of course, a kernel and modules needed to be compiled for i.MX6.
Since it is armv7 imported packages from Debian Wheezy work. It the same procedure as Allwinner and x86 dCore.
So far, I have automated procedures to create a bootable sdcard, boot initrd, and load sce extensions to enable wifi . More to follow...
