to check the status property in their probe routines.
Simplebus used to only instantiate its children whose status="okay"
but that was improper behavior, fixed in r261352. Now that it doesn't
check anymore and probes all its children; the children all have to
do the check because really only the children know how to properly
interpret their status property strings.
Right now all existing drivers only understand "okay" versus something-
that's-not-okay, so they all use the new ofw_bus_status_okay() helper.
then solves because of cache coherency issues. This fixes periodic error
messages on console and command timeouts.
- Patch SATA PHY configuration for 65nm SoCs to improve SNR same as
Linux does.

- current code treats bits 4:7 in 'SATAHC interrupt mask' and 'SATAHC
interrupt cause' as flags for SATA channels 2 and 3
- for embedded SATA controllers (SoC) these bits have been marked as reserved
in datasheets so far, but for some new and upcoming chips they are used for
purposes other than SATA

atamarvell, ataadaptec and atamvsata drivers from ata(4), but provides
many additional features, such as NCQ, PMP, etc.
