With current code, the acrn.efi is inserted between cl bootloader.efi and bzImage.efi that destroyed the chain relationship of cl bootloader and cl bzImage.efi. And the following is current boot flow: UEFI -> cl bootloader.efi -> acrn.efi -> bzImage.efi The purpose of this patch is resume above chain relationship, and make uefi vm return to efi stub context once launched, then continue to call the UEFI API(LoadImage/StartImage) to launch cl bootloader or other bootloaders. So the boot flow will change to be as below: UEFI -> acrn.efi -> cl bootloader.efi -> bzImage.efi After applying this patch, the code related to loading bzImage.efi and getting pe_entry is unnecessary due to the bzImage.efi will not be launched by acrn.efi directly, so it is removed.
