Note that this assumes that the data is in NOR flash. XIP is not
possible with NAND.
NOR is slower than RAM but XIP avoids the decompression and only loads
what is really needed. so in the end most likely you'll win when it
comes to boottime.
There are several pages on elinux.org on boot time improvement.
