So still save and restore the first 128 bytes of DDR memory. * Still save and restoer CCSR registers in kernel, because bootloader doesn't know what register values to restore * Changed copyright and email address from freescale to NXP Please refer to the version 1: [1/4] powerpc/85xx: support sleep feature on QorIQ SoCs with RCPM http://patchwork.ozlabs.org/patch/502549/ [2/4] powerpc: get the physical base address of DCSR http://patchwork.ozlabs.org/patch/502551/ It is removed.
