Linux Kernel Configuration
└─>CPU_ARM926T
In linux kernel since version 2.6.12  
This is a variant of the ARM920. It has slightly different
instruction sequences for cache and TLB operations. Curiously,
there is no documentation on it at the ARM corporate website.

Say Y if you want support for the ARM926T processor.
Otherwise, say N.
