For the U-Boot Fast-Boot test, we used the same image as
in the suspend-resume method. We ran a test with and
without the enhanced-read-speed approach.
Figure 3c shows the results with enhanced read speed.
Relative to the suspend-resume method, the OS spends
less time on resume and much less time on U-Boot initialization.
The result is 47 percent of the suspend-resume
time and 17 percent of normal boot time.
