Yep. I have one now. Make sure your u-boot image also has a TLB1
entry for your "default" CCSRBAR. Further, make sure your BDI init
section doesn't move the CCSRBAR from the default value assumed by
your u-boot image. I had the latter correct, just didn't realize
that a "TLB1 flash invalidate" command to the MMUCSR0 doesn't seem
to honor the 'invalidate protect' in the TLB entry. Everything
works fine when you get all of the ducks in a row :-)
Of course, we should be discussing this on the u-boot list,
not on this one........
