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.

At present we misuse print_cpuinfo() do so CPU init on x86. This is done
because it is the next available call after the console is enabled. But
several arches use checkcpu() instead. Despite the horrible name (which
we can fix), it seems a better choice.
Adjust the various x86 CPU implementations to move their init code into
checkcpu() and use print_cpuinfo() only for printing CPU info.

We don't have the code for this yet. Add a dummy version for now, so that
EFI builds correctly.

We don't support SDRAM init in 64-bit mode since it is essentially
impossible to get into that mode before SDRAM set up. Provide dummy functions
for now. At some point we will need to pass the SDRAM parameters through from
SPL.

At present this is just an ordinary variable. We may consider making it a
fixed register in the future.

There is not much needed at present, but set up a separate directory to put
this code as it grows.
