Debug message was showing timeout value which was passed to start
function but there is a checking if this value can be setup.
The patch is moving this debug printf function below checking.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

Remove busy looping during watchdog reset.
Each polling of W_PEND_WTGR bit ("finish posted
write") after watchdog reset takes 120-140us
on BeagleBone Black board. Current U-Boot code
has watchdog resets in random places and often
there is situation when watchdog is reset
few times in a row in nested functions.
This adds extra delays and slows the whole system.
Instead of polling W_PEND_WTGR bit, we skip
watchdog reset if the bit is set. Anyway, watchdog
is in the middle of reset *right now*, so we can
just return.
This noticeably increases performance of the
system. Below are some measurements on BBB:
- DFU upload over USB 15% faster
- fastboot image upload 3x times faster
- USB ep0 transfers with 4k packets 20% faster

These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.
In the end we will have:
1. dev_read_addr...() - works on devices, supports flat/live tree
2. devfdt_get_addr...() - current functions, flat tree only
3. of_get_address() etc. - new functions, live tree only
All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.
Note this involves changing some dead code - the imx_lpi2c.c file.

Since commit 623d96e89aca6("imx: wdog: correct wcr register settings")
issuing a 'reset' command causes the system to hang.
Unlike i.MX and Vybrid, the watchdog controller on LS102x is big-endian.
This means that the watchdog on LS1021 has been working by accident as
it does not use the big-endian accessors in drivers/watchdog/imx_watchdog.c.
Commit 623d96e89aca6("imx: wdog: correct wcr register settings") only
revelead the endianness problem on LS102x.
In order to fix the reset hang, introduce a reset_cpu() implementation that
is specific for ls102x, which accesses the watchdog WCR register in big-endian
format. All that is required to reset LS102x is to clear the SRS bit.
This approach is a temporary workaround to avoid a regression for LS102x
in the 2015.10 release. The proper fix is to make the watchdog driver
endian-aware, so that it can work for i.MX, Vybrid and LS102x.

with WCR_WDW set, the watchdog won't trigger if we bootet linux and idle
around while the watchdog is not triggered. It seems the timer makes
progress very slowly if at all. I managed to remain 20minutes alive
while the timeout was set to 60secs. It reboots within 60secs if I start
a busyloop in userland (something like "while (1) { }").
While I don't see a reason why the WDT should not be running while the
CPU is in idle, I'm dropping this bit.

Makefile conflicts are due to additions/removals of
object files on the ARM branch vs KBuild introduction
on the main branch. Resolution consists in adjusting
the list of object files in the main branch version.
This also applies to two files which are not listed
as conflicting but had to be modified:
board/compulab/common/Makefile
board/udoo/Makefile
include/configs/omap4_common.h conflicts are due to
the OMAP4 conversion to ti_armv7_common.h on the ARM
side, and CONFIG_SYS_HZ removal on the main side.
Resolution is to convert as this icludes removal of
CONFIG_SYS_HZ.
include/configs/pdnb3.h is due to a removal on ARM side.
Trivial resolution is to remove the file.
Note: 'git show' will also list two files just because
