Are there any memory layout docs for ARM64?

Question

Is there any reference material for where various images should be loaded on ARM-A (aarch64) architectures? For instance, is there anything that says where in memory a bootloader should be placed, where the hypervisor should start, or where trustzone should begin?

Answer 1

The closest reference for this would be SBSA, however:

Note: Compliant software must not make any assumptions about the memory map that might prejudice compliant hardware. For example, the full physical address space must be supported. There must be no dependence on memory or peripherals being located at certain physical locations
