This uses the newly-added dm_gpio_get_values_as_int_base3 function to implement a sysinfo device. The revision map is stored in the device tree. Signed-off-by: Sean Anderson <sean.anderson@seco.com> Reviewed-by: Simon Glass <sjg@chromium.org>

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
|
|
modular board architectures.

bool "Provide a default sysinfo driver for SMBIOS information"
|
|
help
|
|
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.

help
|
|
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.
