		/* The head-file for the Shark
		* by Alexander Schulz
		*
		* Does the following:
		* - get the memory layout from firmware. This can only be done as long as the mmu
		* is still on.
		* - switch the mmu off, so we have physical addresses
		* - copy the kernel to 0x08508000. This is done to have a fixed address where the
		* C-parts (misc.c) are executed. This address must be known at compile-time,
		* but the load-address of the kernel depends on how much memory is installed.
		* - Jump to this location.
		* - Set r8 with 0, r7 with the architecture ID for head.S
