 Available options are:
 
+bootcmd (string)
+	Allows overwriting of the boot command used by U-Boot on startup. If
+	present, U-Boot uses this command instead. Note that this feature can
+	work even if loading the environment is disabled, e.g. for security
+	reasons. See also bootsecure.
+
+bootdelay (int)
+	This allows selecting of the U-Boot bootdelay, to control whether U-Boot
+	waits on boot or for how long. This allows this option to be configured
+	by the build system or by a previous-stage binary. For example, if the
+	images is being packed for testing or a user holds down a button, it may
+	allow a delay, but disable it for production.
+
+u-boot,boot-led (string)
+u-boot,error-led (string)
+	This is used to specify the label for an LED to indicate an error and
+	a successful boot, on supported hardware.
+
+bootsecure (int)
+	Indicates that U-Boot should use secure_boot_cmd() to run commands,
+	rather than the normal CLI. This can be used in production images, to
+	restrict the amount of parsing done or the options available, to cut
+	back on the available surface for security attacks.

 u-boot,efi-partition-entries-offset (int)
 	If present, this provides an offset (in bytes, from the start of a
 	device) that should be skipped over before the partition entries.

+u-boot,no-apm-finalize (bool)
+	For x86 devices running on coreboot, this tells U-Boot not to lock
+	down the Intel Management Engine (ME) registers. This allows U-Boot to

+
 u-boot,no-keyboard (bool)
 	Tells U-Boot not to expect an attached keyboard with a VGA console.

 silent-console (int)
 	If present and non-zero, the console is silenced by default on boot.
