nb/amd/amdfam10: die() on out of bounds reads
These two functions try to access arrays of lengths 32 and 64 at indices of at most 259 and 71 (respectively). Something here is seriously wrong. This code was introduced in 2007, and aside from cosmetic changes, has had no modifications since then. I don't know what this code is supposed to do, and asking around on IRC, no one else did either. Until someone has the interest and time to work on it, let's at least add a die() to prevent the out of bounds access and alert the user that something is wrong.
