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.
|
|
|
|
The current size of the binary blob is expected to be 149 bytes or larger
