Why use a different tag than the -mcpu flag uses? The cases where we
match different names are mostly to due to variations in tools like
uname or if gcc uses a name different from what the cpu is commonly
known as (which may well be the case here). Also, my gcc manual lists
-mcpu=8540 but not 8548.

I have nothing against the patch as such.
