Store kernel .data section compressed in ROM

Linux Kernel Configuration
└─>Boot options
└─>Store kernel .data section compressed in ROM
In linux kernel since version 4.2 (release Date: 2015-08-30)  
Before the kernel is actually executed, its .data section has to be
copied to RAM from ROM. This option allows for storing that data
in compressed form and decompressed to RAM rather than merely being
copied, saving some precious ROM space. A possible drawback is a
slightly longer boot delay.
