Add the power domain DM driver for i.MX8, that it depends on the DTB
power domain trees to generate the power domain provider devices. Users
need to add power domain trees with property "compatible = "nxp,imx8-pd";"

When power on a PD device, the driver will power on its ancestor PD
devices in power domain tree.

When power off a PD device, the driver will check its child PD devices
first. Only if all child PD devices are off, then power off the current PD
device. Then the driver checks sibling PD devices. If sibling PD devices
are off, then it will power off parent PD device.

There is no counter maintained in this driver, but a state to hold current
on/off state. So the request and free functions are empty.

1. Now for ARC boards we print CPU and board info

       a wait list and only this week I've got

arc: Add support for IoT development kit

The DesignWare ARC IoT Development Kit is a versatile platform
that includes the necessary hardware and software to accelerate
software development and debugging of sensor fusion,
voice recognition and face detection designs.

More information is avaialble here [1] and here [2].

The board is based on real silicon with
ARC EM9D-based Data Fusion IP Subsystem.

It sports a rich set of I/O including
 * DW USB OTG
 * DW MobileStorage (used for micro SD-card)
 * GPIO
 * multiple serial interface including DW APB UART
 * ADC, PWM and eFlash, SRAM and SPI Flash memory
 * Real-Time Clock (RTC)
 * Bluetooth module with worldwide regulatory compliance
   (FCC, IC, CE, ETSI, TELEC)
 * On-board 9-axis sensor (gyro, accelerometer and compass)

Extensible with Arduino, Pmod, mikroBUS connectors and a 2x18
extension header.

One of the most interesting features for developers is built-in
Digilent USB JTAG probe so only micro-USB cable is needed!

rockchip: Fix rkimage format for SPL boot over USB

The 'rkimage' format used for booting rockchip boards over USB seems to
have been broken since commit 7bf274b9caab ("rockchip: mkimage: use
imagename to select spl hdr & spl size"). That commit adds an offset of
RK_SPL_HDR_START(=2048) to the location the 'RKxx' header is written
at. However the bootrom expects this header to be the first four bytes of
the image, not at offset 2048. This appears to have been a copy paste
error since the 'rksd' and 'rkspi' image types do require this offset.

Furthermore commit 111bcc4fb6cb ("rockchip: mkimage: pad the header to
8-bytes (using a 'nop') for RK3399"), commit 3d54eabcafec9 ("rockchip:
spl: RK3399: use boot0 hook to create space for SPL magic") and
commit 308277569229 ("rockchip: mkimage: update rkimage to support
pre-padded payloads") changed the way the space for the 'RKxx' header is
allocated and written to the image without adjusting 'rkimage'.

This commit fixes those mistakes and makes it possible to load u-boot SPL
over USB once more.

(Tested on RK3399)
