2020-03-24board: stm32mp1: add finished good in board identifier OTPPatrick Delaunay
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> Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com> Reviewed-by: Patrice Chotard <patrice.chotard@st.com>

2020-01-17stm32mp1: move stboard command in board/st/common directoryPatrick Delaunay
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. Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com> Reviewed-by: Patrice Chotard <patrice.chotard@st.com>
