doc: describe generation of SMBIOS table
SMBIOS is not x86 specific. So we should have an architecture independent
page describing it.

+SMBIOS tables
+=============
+
+The System Management BIOS (SMBIOS) table is used to deliver management
+information from the firmware to the operating system. The content is
+standardized in [1]_.
+
+In Linux you can use the dmidecode command to view the contents of the SMBIOS
+table.
+
+When booting via UEFI the SMBIOS table is transferred as an UEFI configuration
+table to the operating system.
+
+To generate SMBIOS tables in U-Boot, the CONFIG_GENERATE_SMBIOS_TABLE option
+must be enabled. The easiest way to provide the values to use is via the device
+tree. For details see
+:download:`smbios.txt <../device-tree-bindings/sysinfo/smbios.txt>`.
