In the next commit, CONFIG_EFI_SETUP_EARLY will become mandated in order to support dynamic enumeration of efi_disk objects. This can, however, be problematic particularly in case of file-based variable storage (efi_variable.c, default). Non-volatile variables are to be restored from EFI system partition by efi_init_variables() in efi_init_obj_list(). When efi_init_obj_list() is called in board_init_r(), we don't know yet what disk devices we have since none of device probing commands (say, scsi rescan) has not been executed at that stage. So in this commit, a preparatory change is made; efi_init_obj_list() is broken into the two functions; * efi_init_early(), and * new efi_init_obj_list() Only efi_init_early() will be called in board_init_r(), which allows us to execute any of device probing commands, either though "preboot" variable or normal command line, before calling efi_init_obj_list() which is to be invoked at the first execution of an efi-related command (or at efi_launch_capsules()) as used to be.
