Update the command stboard to support the updated coding of OTP 59 with
finished good.
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>

Read the value directly from the OTP and no more of the shadows
to avoid the need of reboot after stboard command to have correct value.

Move the ST command in board/st/common, as this command is only used
by ST board. Prepare the support in U-Boot of boards with STM32MP15x
SOC but not STMicroelectronics.
