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.
