As of now this flag assumes that the bootloader is in LE mode. It is 
left to the kernel to switch to BE mode. This flag makes the kernel set 
necessary flags in SCTLR registers on entry.

This is a generic patch for the architecture. Each driver needs to make 
necessary changes keeping the kernel endianness in mind. We have tested 
these patches on our X-Gene platform.
