-/* 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
