This patch makes the Service OS bootloader configurable by passing
a command-line argument to 'acrn.efi' when setting up the EFI
bootloader using, e.g., 'efibootmgr'. If no argument is passed, the
default bootloader used is: "\EFI\org.clearlinux\bootloaderx64.efi".
This is the default bootloader/setting used by Clearlinux and is set
in the bsp/uefi/include/bsp/bsp_cfg.h file (via the
CONFIG_UEFI_OS_LOADER_NAME define)
The general format of the argument is: "bootloader=<\path\to\bootloader>".
As a concrete example, imagine the following set-up:
* You have installed the Service OS (bare-metal for now)
* Bootloader is "\EFI\org.clearlinux\bootloaderx64.efi"
* Boot device is '/dev/sda'
* EFI System Partition (ESP) is '1'
* You put the ACRN hypervisor under "\EFI\acrn\"
To change the default boot entry to boot the ACRN hypervisor, enter:
# efibootmgr -c -l "\EFI\acrn\acrn.efi" -d /dev/sda -p 1 \
-L "ACRN Hypervisor" -u "bootloader=\EFI\org.clearlinux\bootloaderx64.efi"
And reboot your machine.
