[U-Boot] [PATCH V2 00/11] imx: introduce rdc and boot auxiliary core

[Peng Fan]

From: Peng Fan <peng.fan at 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.

Since we also sometimes put the M4 image in QSPI to let M4 directly fecth
code in the memory mapped QSPI space, we can not support such as libz
compressed image.
