In amd/{persimmon,inagua} and derived boards avoid using AGESA
reimplementation of memcpy as following the reasoning in:

Change `sizeof(type) * n`, where n is the number of array
elements, to `sizeof(variable)` to directly get the size of the
variable (struct, array). Determining the size by counting array
elements is error prone and unnecessary.
Rudolf Marek’s patch »ASUS F2A85-M: Correct and clean up PCIe
config« [1] contains the same change and is ported over. In
the commit message Rudolf makes the following comment.
»Not sure why the copy is needed instead of direct reference.
Maybe it has something to do with CAR?«
Testing on the ASRock E350M1, no regressions were noticed.

In `PlatformGnbPcie.c` AGESA functions are used to reserve memory
space to save the PCIe configuration to. This is the
With the following definitions in `AGESA.h`
$ more src/vendorcode/amd/agesa/f14/AGESA.h
[…]
/// PCIe port descriptor
typedef struct {
IN UINT32 Flags; /**< Descriptor flags
* @li @b Bit31 - last descriptor in complex
*/

IN PCIe_PORT_DATA Port; ///< PCIe port specific configuration info
} PCIe_PORT_DESCRIPTOR;
/// DDI descriptor
typedef struct {

IN PCIe_ENGINE_DATA EngineData; ///< Engine data
IN PCIe_DDI_DATA Ddi; ///< DDI port specific configuration info
} PCIe_DDI_DESCRIPTOR;
/// PCIe Complex descriptor
typedef struct {
IN UINT32 Flags; /**< Descriptor flags
* @li @b Bit31 - last descriptor in topology
*/
IN UINT32 SocketId; ///< Socket Id
IN PCIe_PORT_DESCRIPTOR *PciePortList; ///< Pointer to array of PCIe port descriptors or NULL (Last element of array must be terminated with DESCRIPTOR_TERMINATE_LIST).
IN PCIe_DDI_DESCRIPTOR *DdiLinkList; ///< Pointer to array DDI link descriptors (Last element of array must be terminated with DESCRIPTOR_TERMINATE_LIST).
IN VOID *Reserved; ///< Reserved for future use
} PCIe_COMPLEX_DESCRIPTOR;
[…]
memory has to be reserved for the `PCIe_COMPLEX_DESCRIPTOR` and,
as two struct members are pointers to arrays with elements of type
`PCIe_PORT_DESCRIPTOR` and `PCIe_DDI_DESCRIPTOR`, space for these
times the number of array elements have to be reserved:
a + b * 5 + c * 2.
sizeof(PCIe_COMPLEX_DESCRIPTOR)
+ sizeof(PCIe_PORT_DESCRIPTOR) * 5
+ sizeof(PCIe_DDI_DESCRIPTOR) * 2;
But for whatever reason parentheses were put in there making this
calculation incorrect and reserving too much memory.
(a + b * 5 + c) * 2
So, remove the parentheses to reserve the exact amount of memory
needed.
The ASRock E350M1 still boots with these changes. No changes were
observed as expected.
Rudolf Marek made this change as part of his patch »ASUS F2A85-M:
Correct and clean up PCIe config« [1]. Factor this hunk out as it
affects all AMD Brazos and Trinity based boards.

Step 2: change the Persimmon code to adapt it to the new board's hardware.
The FrontRunner-AF is a PC/104+ form factor embedded board:
- AMD Fusion G-T56N (1.65 GHz dual core) or T40R (1 GHz single core) APU
- DDR3 SO-DIMM socket (1.5 or 1.35V)
- VGA and LVDS (via Analogix ANX3110)
- AMD A55E (Hudson-E1) southbridge
- 6x USB 2.0
- 1x SATA, 1x CFast socket
- HD Audio (via Realtek ALC886)
- PCI and ISA (via ITE IT8888)
- NEC uPD78F0532 microcontroller on I2C ("SEMA")
- Intel I210 GbE (on APU PCIe x1)
- SMSC SCH3112 SIO
- PS/2
- 2x RS232/485
- 2x SST 25VF032B (SO8, soldered) 4 MB SPI flash (BIOS and failsafe BIOS)

Step 1: copy all files unmodified from Persimmon. This makes it much
easier later to see how the two boards actually and deliberately differ
when porting bugfixes from one to the other. Git's copy detection is
imperfect (and slow).
