Hmmm, are you doing some substantial changes to this file
that entitles you to add your Copyright here? Its mostly
a move of an existing file, right?

This does not seem to be based on top of the latest mainline
git version. We are using the new SPDX tags now at the beginning
of the file now - same as Linux does:

$ cat arch/arm/mach-mvebu/sata.c
// SPDX-License-Identifier: GPL-2.0+
/*

#include <common.h>
#include <ahci.h>
#include <dm.h>
...

So please base your patch series on top of the latest mainline
git version and resubmit. And please add my:
