针对IXP425处理器的Bootloader（汇编部分）实现

Bootloader是嵌入式开发的最先部分，各种Bootloader的功能也各异，其中成熟的有redbcot，ubcot等。在开发一个新的系统时无法直接把这些成熟的代码拿来使用，而重新写一个Bootloader又太浪费资源，因此移植就成了首选。Bootloader的移植工作主要集中在汇编代码部分，弄清了汇编部分的实现，其C语言部分的修改工作就不多了。文中就是以Intel IXP425处理器为实例解析了Bootloader的汇编代码执行过程。

Bootloader(Assemble Language Part)for IXP425 Network Processor

Bootloader is the first part of developing an embedded system. There are too much sorts of Bootloader like redboot, uboot etc. Although have these famous Bootloaders, we can't use it directly in our system. So porting a Bootloader on different system is a goog choice and writing a new Bootloader is too much waste.When porting a Bootloader we focus on assemble language part, if fullfill the assemble lanaguage part there will be no much work left.For we can use the C language part without much change.This article gives and parses the detail of the Bootloader's assemble language part for IXP425 network processor.
