The pm8001 can be delivered as a standalone product with flash-programmed
firmware images, or without the flash present requiring the driver to upload
the images into the chip's RAM and then run. This is called HDA mode.

We add support for this firmware upload in the enclosed patch. We try some
basic initialization checks of the Firmware, and if it appears dead, we make
the assumption the adapter must in-fact be halted in this HDA mode. The
Firmware images themselves have not been cleared for open-release by PMC, but
they are available in OpenSolaris <hint hint>. PMC's rationalization for not
wanting an open-release of the Firmware Images is that they do not want to
take support calls except from paying OEMs (such as Xyratex) that are embedding
PMC product into the motherboards and thus may have a tested combination of
Firmware and Hardware. Please respect this sentiment. Images are expected in:

/lib/firmware/aap1img.bin
/lib/firmware/ilaimg.bin
/lib/firmware/iopimg.bin
/lib/firmware/istrimg.bin

using the exact same naming convention as PMC and in OpenSolaris (and its
followon children) for these image files.
