I wonder if there's some kind of memory corruption going on; IIRC I 
checked out the committed version of this patch in u-boot/master's 
history, and 3 tests failed, but by the time you reach the current 
u-boot/master, only 2 tests fail, and I don't think there were any more 
spmi-related commits between the two. That would indicate some kind of 
outside interference, which would also be consistent with your unusual 
findings.
