Write down this series of u-boot transplants, but also deepen your understanding. In fact, there are a lot of great gods on the Internet, and a lot of solutions are given. I also use them as a reference. In contrast, I would add some of my own understandi

The BIOS era is coming to an end! This is not a small fabrication, but a trace to follow. As we all know, bios as a computer boot software, has been nearly 30 years of history. In fact, early in research and development, the fate of the BIOS has been doomed, the technical staff did not intend to keep it too long cycle, sooner or later there will be eliminated one day. In the 2011, this trend is becoming more obvious, many new computers have adopted or
