Now ACRN supports direct boot mode, which could be SBL/ABL, or GRUB boot. Thus the vboot wrapper layer can be removed and the direct boot functions don't need to be wrapped in direct_boot.c: - remove call to init_vboot(), and call e820_alloc_memory() directly at the time when the trampoline buffer is actually needed. - Similarly, call CPU_IRQ_ENABLE() instead of the wrapper init_vboot_irq(). - remove get_ap_trampoline_buf(), since the existing function get_trampoline_start16_paddr() returns the exact same value. - merge init_general_vm_boot_info() into init_vm_boot_info(). - remove vm_sw_loader pointer, and call direct_boot_sw_loader() directly. - move get_rsdp_ptr() from vboot_wrapper.c to multiboot.c, and remove the wrapper over two boot modes.

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/
