Hi Mario,

Thank you for patch submission.

Please remember to always include a commit message body describing your patch in
more detail than the single line subject. It should provide enough detail to get
someone unfamiliar with these changes to understand why they were needed  and
how you intended to go about fixing it. This is the context needed to review the
patch.

In addition to adding X51 R3 as a separate platform from the previous X51 Family
(no R1 R2), this patch also appears to introduce various whitespace changes. Any
change made within the patch should read back to some comment in the changelog.
