The best way to make this work IMHO would be for us not to accept any
new
feature addition patches as long as there are warnings reported in the
test results.  The only real exception that I would foresee is if those
warnings are due to something outside of our control, e.g., a crappy
bootloader, as I suspect the USB_OTG initiator warnings are for the
CM-T3517.
I doubt this is related to the bootloader. I have the suspicion that is
actually
a bug in linux but only triggered depending on whether the ROMcode setup
the USB OTG or not. Here is some data to backup my statement:
Turns out my suspicion was wrong. This is what I know at the moment,
depending on the bootpins, u-boot will trigger a bad access when loading
a file over ethernet, but only the first time. Clearing the pending interrupt
before booting linux make the "USB_OTG address hole seen" go away.
Oh, too bad.  I had been hoping that you were right and that I was wrong 
;-)  I'll try this on the CM-T3517 here.
I used your debugging technique here and was able to reproduce your 
results - with one difference:

http://www.pwsan.com/omap/testlogs/test_v4.1-rc6/20150607194102/boot/cmt3517/cmt3517_log.txt

The interconnect error was logged upon the first interaction with the 
network.  In my case this was with the U-boot 'dhcp' command.  The pending 
interrupt bit was cleared before loading the kernel via tftp, and the 
interrupt bit was not set again, even after a tftp load.
