Dear Mike,
In message OF532F17EB.D2119CC3-ON852576F0.0072502F-852576F0.00725A73@apcc.com you wrote:
What is the purpose of CONFIG_PCI_BOOTDELAY? I am using uboot version
Adding a delay so the PCI controllers can come up and stabilize.
Specifically in my case, all the resets on my board have occurred well before (500 msec) this portion of the code would execute, so it would seem safe to say that any peripherals like PCI controllers would be satisfied reset-wise.
500ms is not safe. We have seen cases (for example on 440SP / 440SPe) where 5...10 seconds (!) were needed.
Best regards,
Wolfgang Denk
