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.

d024236e5a Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR
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.

026a8b96bd ARM: Tegra186: calculate load addresses at boot
In the presence of potentially fragemented memory, we cannot hard-code
addresses into environment variables such as kernel_addr_r. Instead, we
must calculate those addresses at run-time based on available memory
locations. Implement the code to perform such runtime calculation, based
on requirements described in environment variables, to allow the user
full control over the allocation.

00caae6d47 env: Rename getenv/_f() to env_get()
We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.

Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

a182e69d79 ARM: tegra: allow passing cboot DTB to the kernel
Some users may wish to pass the cboot-supplied DTB to the booted kernel
rather than having U-Boot load the DTB itself. To allow this, expose the
address of the cboot-supplied DTB in environment variable $fdt_addr. At
least when using extlinux.conf, if the user doesn't explicitly specify
which DTB to pass to the kernel, U-Boot passes the DTB referred to by
this variable.

2b950f3aea ARM: tegra: configure Ethernet address on Tegra186
On Tegra186, the bootloader which runs before U-Boot passes the Ethernet
MAC address to U-Boot using device tree. Extract this value and write it
to the environment, so that the Ethernet uclass picks it up and uses it
for the built-in Ethernet device.
