To run this in QEMU please run 
qemu-system-aarch64 -M raspi3 -drive file=raspi.iso,if=sd,format=raw -kernel kernel8.img -serial stdio

I would like to acknowledge bztsrc for their awesome tutorials without them most of this wouldn't have been done. Certainly not the sd and fat part.
I would also like to thank LdB-ECM for their massive contribution to this project without them this kernel wouldn't be capable of multitasking and semaphores would have been impossible.
