I don't know why, but this patch has nothing to do with my original one.
Can you stick to the original code?
Of course, if you have valid comments or need to add extra data, you 
can, but in this case, I do not see any needed change.

The original comment is missing.

If that physical address is not used elsewhere, and it should be the 
case, there is no need to create a define for it. That's why the 
physical address was directly used here.
There is no added value to create a define for that.

The order is different than the previous one.
