59b0d7d839 bdinfo: arm: Move ARM-specific info into its own file
We don't really want to have ARM-specific code in a generic file. Create
a new arch-specific function to hold it, and move it into that.

Make the function weak so that any arch can implement it.

655f17ff7d bdinfo: Export some basic printing functions
At present the functions to print a number and a frequency are static. We
want to move some of the code in here to an arch-specific file. For
consistency that code should use these same functions. So export them with
an appropriate name.

ba974a0137 board: Add a gd flag for chain loading
When U-Boot is run from another boot loader, much of the low-level init
needs to be skipped.

Add a flag for this and adjust ll_boot_init() to use it.

941338725d common: Move relocate_code() to init.h
This is an init function so move it out of the common header. Avoid using
the typedef so that we don't have to include the global_data header file.

Also tidy up the function style in comments while we are here.

5764ea2df4 Revert "board_f: Use static print_cpuinfo if CONFIG_CPU is active"
This reverts commit c0434407b5.

It turns out commit c0434407b5 broke some boards which have DM CPU
driver with CONFIG_DISPLAY_CPUINFO option on. These boards just fail
to boot when print_cpuinfo() is called during boot.

Fixes are already sent to ML and in u-boot-dm/next, however since
we are getting close to the v2018.11 release, it's safer we revert
the original commit.

This commit should be reverted after v2018.11 release.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.
