		+	To reduce booting time,we use falcon mode to load kernel directly,should optimize kernel and rootfs, you can refer following steps:
		+
		+	=== Enter falcon mode ===
		+
		+	1: replace zImage with uImage by uboot env:
		+	<pre>setenv image uImage
		+	fatload mmc ${mmcdev}:${mmcpart} ${fdt_addr} ${fdt_file}
		+	fatload mmc ${mmcdev}:${mmcpart} ${loadaddr} ${image}
		+	setenv bootargs console=${console},${baudrate} ${smp} root=${mmcroot} ${bootargs}
		+	mmc write ${loadaddr} 0x5D87FF 0x4000
		+	mmc write 18000000 0x5D7FFF 0x800
		+	</pre>
		+
		+	2: prepare args
		+	<pre>spl export fdt ${loadaddr} - ${fdt_addr}
		+	setenv boot_os 1 && saveenv && reset</pre>
		+
		+	=== Optimize kernel ===
		+
		+	1: Specifies the root file system format in uboot env: rootfstype=ext4
		+
		+	2: reduce debug message in kernel booting by uboot env: quiet
		+
		+	3: eliminate unneeded features/drivers by menuconfig
		+
		+	=== Optimize rootfs ===
		+
		+	1: reduce partition size on SDcard
		+
		+	2: stop the unessential services
		+
		+	3: change /etc/inittab
		+
		+	S: single-user mode<br/>id:S:initdefault:<br/>s1::sysinit:mount -t proc proc /proc<br/>s2::sysinit:mount -t sysfs sysfs /sys<br/>s3:S:respawn:/bin/ash < /dev/ttymxc0 > /dev/ttymxc0
