Description: arm9的bootloader,适合通用2410x平台
vivi.pal(20051228)支持tv输出和vga输出，vclk为26.25mhz
vivi(20060330)支持vga输出和tv输出，vclk为25mhz
以上两个vivi均编译自vivi-br-release(20051228).tar.gz
在两个不同vivi间切换的方法是在源文件“/include/platform/smdk2410.h”中打开或者取消对PAL640480宏的定义：
#define PAL640480
默认该句是注释掉的，编译得到的vivi的vclk为25mhz
ch7005手册中要求640x480的pal输出时vclk为26.25mhz，但实践中发现并不需要完全等与这个频率，有时候vivi(20051228)的pal效果更好，具体使用哪个参数用户可以多比较尝试，也可以尝试修改成其他的频率。-arm9 Bootloader, Definitive 2410 x suitable platform vivi.pal (20051228) support tv vga output and losers that vclk to 26.25mhz 14:57 (20060330) support tv vga output and exports, vclk for more than two 25mhz were compiled from 14:57 14:57 - br-release (20 051,228). tar.gz 14:57 in the two different ways of switching between the source document "/ incl. ude/platform/smdk2410.h "open or cancel right PAL64048 0-definition : # define default PAL640480 comment out of the sentence.
