Add support for the Arm Versatile Express config bus that is
being used for exposing various subsystems via a generic
configuration bus. This driver adds support for generating
transactions on this configuration bus and can be used by
other drivers to abstract the communication with the actual
function providers.

Instead of manually specifying CONFIG_SYS_EXTRA_ENV_RELOC
for every board that needs it, it shouldn't hurt to let
initr_reloc_global_data() always relocate gd->env_addr
unless we know this pointer is outside the initial binary.

To achieve this, the relocation is omitted if
CONFIG_ENV_ADDR is defined (and ENV_IS_EMBEDDED is not).

After a test has failed, test/py drains the U-Boot console log to ensure
that any relevant output is captured. At this point, we don't care about
detecting any additional errors, since the test is already known to have
failed, and U-Boot will be restarted. To ensure that the test cleanup code
is not interrupted, and can correctly terminate the log sections for the
failed test, ignore any exception that occurs while reading the U-Boot
console output during this limited period of time.

Here we do a couple of impovements for all ARC boards
as well as introduce yet another developemnt board.

1. Now for ARC boards we print CPU and board info
   which is useful for users and helps with
   analysis of logs "post-mortem".

2. Synopsys IoT development kit support is added
   This one might bw a bit too late as we're past RC1
   but:
    1) This doesn't affect any other arches etc
       as we change purely ARC code.
    2) I've got a chance to talk about U-Boot on
       IoT platforms during ELCE (my proposal was on
       a wait list and only this week I've got
       an update and invitation to talk) so it would
       be good to have this board as a primer in upstream
       code-base by the time of ELCE 2018.
    3) For complete support of IoT devkit I'm yet to
       significantly rework regmap subsystem in U-Boot
       but that's a different topic and hopefully it will
       be done sometime soon... though not this release
       cycle for sure.

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!

The 'rkimage' format used for booting rockchip boards over USB seems to
have been broken since commit 7bf274b9 ("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 111bcc4f ("rockchip: mkimage: pad the header to
8-bytes (using a 'nop') for RK3399"), commit 3d54eabc ("rockchip:
spl: RK3399: use boot0 hook to create space for SPL magic") and
commit 30827756 ("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.

OP-TEE is an open source trusted OS, in armv7, its loading and
running are like this:
loading:
- SPL load both OP-TEE and U-Boot
running:
- SPL run into OP-TEE in secure mode;
- OP-TEE run into U-Boot in non-secure mode;

To make code simple, it would be fine to use IH_OS_TEE for the
os tyle in TPL(just like IH_OS_LINUX is using both in SPL and U-Boot).
