MIPS: Netlogic: Add nlm_get_boot_data() helper
This moves the calculation and casting needed to access the CPU initialization data to a function nlm_get_boot_data() Signed-off-by: Jayachandran C <jchandra@broadcom.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/5426/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
