Aarch64 low-level lab

Here you can find some low-level Aarch64 code that can run on the bare processor inside a virtual machine, i.e. prior to any firmware or an OS.

The repo produces a position-independent executable able to relocate itself, log the register values to the PL011 port, and can enable the MMU. The 4KiB translation granule size is used, and the optimal mix of page sizes is chosen when mapping. There are tests present, and, in particlular, one test that generates code on the fly.

The code showcases using semihosting on Aarch64, too.
