[1.3.110] SATA/SAS SGPIO Header

[1.3.111] The HSBPs will support SGPIO interface (SFF-8485).
On S210-MBT2W the SGPIO signals are passed through the
sideband signal pins on the SFF-8087 connectors and do not
require individual SGPIO headers.

[1.3.113] HSBP I2C Bus

[1.3.114] The baseboard must add a 3pin I2C header to base-
board for a bus to the HSBP. The 3-pin header on the board
must implement MLX 22-43-6030 (white housing). This header
does not contain any addressing wires since the circuits on the
HSBP will handle the addressing. The proposal is to daisy
chain the I2C for up to 3 HSBPs in a single server.

[1.3.115] This same I2C bus will also go to a 4-pin header with
3.3V STBY that is intended to be used for third party fan control
circuits using a Maxim 72408 controller. The 4-pin connector
will use FOX HF4504E and must have 30u gold plating. This is
in addition to maintaining the typical IPMB header in case we
want to offer this for 3rd party chassis HSBPs.
