So, there's a RedBoot bug in there somewhere, I suspect, but I don't care -
it works now.

Uh, baffled. No changes in the pkgconf headers (or CDL) which should
be even remotely related.

before caches are enabled... Guess it could be done earlier, but
hal_if_init call is just before caches get enabled...

(including flash drivers would pull in diag_printf clients and thus the init
