LS1028A GPU

[rhaas]

I am working on a new avoinics product that uses an LS1028A. This product does not use the GPU. Future products will use the GPU. I plan on using a PBI command or a HW strap to turn the GPU off.

My question is there a method to verify the GPU is off?  I need to verify that the GPU is off because of certification requirements.

Thank you

Device disable register6 :: DEVDISR6 (1E0_0084) --> Customer can disable the GPU by using this register.
