currently, ACRN hypervisor can either boot from sbl/abl or uefi, that's why we have different firmware method under bsp & boot dirs. but the fact is that we actually have two different operations based on different guest boot mode: 1. de-privilege-boot: ACRN hypervisor will boot VM0 in the same context as native(before entering hypervisor) - it means hypervisor will co-work with ACRN UEFI bootloader, restore the context env and de-privilege this env to VM0 guest. 2. direct-boot: ACRN hypervisor will directly boot different pre-launched VM(including SOS), it will setup guest env by pre-defined configuration, and prepare guest kernel image, ramdisk which fetch from multiboot modules. this patch is trying to: - rename files related with firmware, change them to guest vboot related - restruct all guest boot stuff in boot & bsp dirs into a new boot/guest dir - use de-privilege & direct boot to distinguish two different boot operations this patch is pure file movement, the rename of functions based on old assumption will be in the following patch.

ACRN Hypervisor ############### The open source `Project ACRN`_ defines a device hypervisor reference stack and an architecture for running multiple software subsystems, managed securely, on a consolidated system by means of a virtual machine manager. It also defines a reference framework implementation for virtual device emulation, called the "ACRN Device Model". The ACRN Hypervisor is a Type 1 reference hypervisor stack, running directly on the bare-metal hardware, and is suitable for a variety of IoT and embedded device solutions. The ACRN hypervisor addresses the gap that currently exists between datacenter hypervisors, and hard partitioning hypervisors. The ACRN hypervisor architecture partitions the system into different functional domains, with carefully selected guest OS sharing optimizations for IoT and embedded devices. You can find out more about Project ACRN on the `Project ACRN documentation`_ website. .. _`Project ACRN`: https://projectacrn.org .. _`ACRN Hypervisor`: https://github.com/projectacrn/acrn-hypervisor .. _`Project ACRN documentation`: https://projectacrn.github.io/
