In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
If you need to specify a specific endianness for access to flash
chips, or if you wish to reduce the size of the kernel by including
support for only specific arrangements of flash chips, say 'Y'. This
option does not directly affect the code, but will enable other
configuration options which allow you to do so.

If unsure, say 'N'.
