TODO: Fill this out
First, it backs up the original kernel base, and then relocates the kernel for
<pre>
// Backup kernel_base argument for use later
original_kernel_base = kernel_base;
// Move kernel elsewhere in DRAM if needed (unused in practice?)
// This is maybe to support reserving unused memory for a second OS/hypervisor?
KernelLdr_RelocateKernelPhysically(&kernel_base, &kernel_map);

TODO: More stuff
== KernelLdr_RelocateKernelPhysically ==
This retrieves memory layout information from the secure monitor, and adjusts the kernel's physical location if necessary.
<pre>
adjusted_kernel_base = KernelLdr_GetAdjustedKernelPhysicalBase(*p_kernel_base);
if (adjusted_kernel_base != *p_kernel_base) {
// Copy data to adjusted destination
memmove(adjusted_kernel_base, *p_kernel_base, (*p_kernel_map)->data_end_offset);
// Adjust pointers.
kernel_base_diff = adjusted_kernel_base - *p_kernel_base;
*p_kernel_base = (uintptr_t)*p_kernel_base + kernel_base_diff;
