v1.1 allows finer grained tuning of the SSC (spread-spectrum-clocking) settings for SAS and SATA. See notes in probe_roms.h v1.3 allows the attenuation of the attached cables to be specified to the driver in terms of 'short', 'medium', and 'long' (see probe_roms.h). These settings (per phy) are retrieved from the platform oem-parameters (BIOS rom), the fallback firmware blob, or via a module parameter override.

This defines the temporary binary blow we are to pass to the SCU driver to emulate the binary firmware that we will eventually be able to access via NVRAM on the SCU controller.
