> The ST product codification have several element
> - "Commercial Product Name" (CPN): type of product board (DKX, EVX)
>   associated to the board ID "MBxxxx"
> - "Finished Good" or "Finish Good" (FG):
>   effective content of the product without chip STM32MP1 (LCD, Wifi, …)
> - BOM: cost variant for same FG
>   (for example, several provider of the same component)
> 
> For example
> - commercial product = STM32MP157C-EV1
> - Finished Good = EVA32MP157A1$AU1
> 
> Booth information are written on board and these information is also saved in
> OTP59:
> 
> bit [31:16] (hex) => Board id, MBxxxx
> bit [15:12] (dec) => Variant CPN (1....15) bit [11:8]  (dec) => Revision board (index
> with A = 1, Z = 26)
> bit [7:4]   (dec) => Variant FG : finished good (NEW)
> bit [3:0]   (dec) => BOM (01, .... 255)

> The updated command is:
>   stboard [-y] <Board> <VarCPN> <Revision> <VarFG> <BOM>
> 
> And the displayed STMicroelectronics board identification is:
>   Board: MB<Board> Var<VarCPN>.<VarFG> Rev.<Revision>-<BOM>
