+SMBIOS tables
+-------------
+
+To generate SMBIOS tables in U-Boot, for use by the OS, enable the
+CONFIG_GENERATE_SMBIOS_TABLE option. The easiest way to provide the values to

+x86 board driver
+================
+
+This driver allows providing board-specific features such as power control
+GPIOs. In addition, the SMBIOS values can be specified in the device tree,
+as below:
+
+An optional 'smbios' subnode can be used to provide these properties.
+
+Optional properties:
+ - manufacturer: Product manufacturer for system / baseboard
+ - product: Product name
+ - version: Product version string
+ - serial: Serial number for system (note that this can be overridden by
+ the serial# environment variable)
+ - sku: Product SKU (Stock-Keeping Unit)
+ - family: Product family
+ - asset-tag: Asset tag for the motherboard, sometimes used in
organisations
+ to track devices
+
+
+Example:
+
+ board {
+ compatible = "google,coral";
+
+ smbios {
+ manufacturer = "Google";
+ product = "Coral";
+ version = "rev2";
+ serial = "123456789";
+ sku = "sku3";
+ family = "Google_Coral";
+ asset-tag = "ABC123";
+ };
+ };
