Got a note from my customer, and did verify that the link is dead and it is a pretty important file:
I am trying to locate the following resource: Sitara Processor Power Distribution Networks: Implementation and Analysis(SPRAC76)
http://www.ti.com/lit/pdf/sprac76
The AM57xx series families refer to this document and clearly state that TI ONLY supports designs that follow the board design guidelines contained in said report!
So I am rather anxious to get my hands on it!
