There is one more test I should have done before sending my previous
email.  I added the patch that is planned to fix the problem I
reported on top of:

  76b069b1cb20 spmi: spmi-pmic-arb: enable the SPMI interrupt as a wakeup source

which is the last patch in the series that included the patch that
I reported a problem with.  My board boots fine at that point,
so I am fairly confident that my further boot issues have yet
another cause, and that the fix on its way upstream should fix
the specific problem that I reported.
