From: Peng Fan <peng.fan@nxp.com>

To i.MX6SX and i.MX7D, there is a M4 core embedded. Resources
can be shared or occupied exclusively by setting Resource
domain controller between A9/7 core and M4 core.

Refer "Chapter 52 Resource Domain Controller (RDC)" of i.MX 6SoloX
RM and "Chapter 3.2 Resource Domain Controller (RDC)" of i.MX 7Dual RM
for detailed infomation.

To bootup M4 core, a new command 'bootaux' is introduced. To i.MX7D,
we need to setting RDC when booting M4 core, so make RDC and boot
auxiliary core patches into one patch set.
