The Renesas R-Car Gen3 development kits contain board ID EEPROM. This driver parses out the board ID and revision out of that EEPROM and exports it e.g. for the board-info print on boot.

Support methods to query hardware configurations from internal

mechanisms (e.g. reading GPIO values, determining the presence of

devices on busses, etc.). This enables the usage of U-Boot with

Some boards want to specify the manufacturer or product name but do
|
|
not need to have their own sysinfo driver. This includes a default
|
|
one which provides a way to specify this SMBIOS information in the

|
devicetree, without needing any board-specific functionality.

Support querying gpios to determine board revision. This uses gpios to
|
|
form a ternary number (when they are pulled-up, -down, or floating).
|
|
This ternary number is then mapped to a board revision name using
|
|
device tree properties.
