* This function is called by bdinfo to print detail board information.
* As an exmaple for future board, we organize the messages into
* several sections. If applicable, the message is in the format of
* <name> = <value>
* It should aligned with normal output of bdinfo command.
*
* Voltage: Core, DDR and another configurable voltages
* Clock : Critical clocks which are not printed already
* RCW : RCW source if not printed already
* Misc : Other important information not in above catagories
