Boot ROM code creates TLB entries for 3.5G space before entering the u-boot. Earlier we were deleting these entries after early initialization of CPU. In recent past, code has been added to invalidate all these entries before relocation of u-boot code. So this code to delete TLB entries after CPU initialization is no longer required.
