mainboard: Add AMD DB-FT3b (Olive Hill+) with Steppe Eagle SoC
Create a new mainboard based on the AMD DB-FT3 development board
(Olive Hill) using an AMD Steppe Eagle processor. The actual DB-FT3
and DB-FT3b mainboards are identical except for the soldered-down
SoC device. The new AMD DB-FT3b development board (Olive Hill+)
features:
* Mini-ITX form factor
* 2x DisplayPort
* 1x VGA
* Integrated Realtek RTL8111-compatible Ethernet
* 2x USB 3.0 ports
* 2x USB 2.0 externally-accessible ports
* 2x USB 2.0 internally-accessible ports (via headers)
* micro LPC header
* Integrated platform security processor
* 2x Full-size DDR3 DIMM support (1 channel)
* Realtek ALC272 HD audio
* 2x SATA ports
* 1x SD card slot
* 1x PCIe (x4) slot
* 1x mini-PCIe slot
* 8-pin programming header
Eliminate the extraneous headers included in PlatformGnbPcie.
BiosCallOuts normally has a bunch of extraneous references to the
mainboard name. Rather than correct the spelling of a bunch of
instances, just get rid of them.
For the most part, use the Olive Hill ACPI definitions since the
DB-FT3b board ("Olive Hill+") and Olive Hill are the same board
with different processors.
Change some function prototypes for functions without parameters
to void instead of AGESA's VOID. There are no parameters for
these functions, so there is no real reason to use VOID.
S3 and fan control are not supported. HD audio is not working.
