Linux Kernel Configuration
└─>Support ARM V6K processor extensions
In linux kernel since version 2.6.15 (release Date: 2006-01-02)  
Say Y here if your ARMv6 processor supports the 'K' extension.
This enables the kernel to use some instructions not present
on previous processors, and as such a kernel build with this
enabled will not boot on processors with do not support these
instructions.
