It is a simple firmware that is designed to be launched from anything that supports loading ELF binaries and running them with the PVH booting standard

The purpose is to be able to use this firmware to be able to load a bootloader from within a disk image without requiring the use of a complex firmware such as TianoCore/edk2 and without requiring the VMM to reuse functionality used for booting the Linux kernel.

Currently it will directly load a kernel from a disk image that follows the Boot Loader Specification

There is also minimal EFI compatibility support allowing the boot of some images that use EFI (shim + GRUB2 as used by Ubuntu).

New Features and Improvements:

* AArch64 support
* RISC-V support
* Improved PCI BAR handling
* Improved EFI support
* Improved integration tests
* Improved CI/CD workflows
