5.4.1. Before You Begin Installation Requirements

The following section assumes that flash memory is used as the storage device for the firmware on your board. If this is not the case, the following instructions will not work - you will probably have to replace the storage device (probably ROM or EPROM) on such systems to install or update U-Boot. Board Identification Data

All %BOARDNAME% boards use a serial number for identification
purposes. Also, all boards have at least one ethernet (MAC) address
assigned. You may lose your warranty on the board if this data gets
lost. Before installing U-Boot or otherwise changing the software
configuration of a board (like erasing some flash memory) you should
make sure that you have all necessary information about such data.
