怎么修改裸机运行的时钟频率呢？我在 soc_cfg.h文件里面发现以下东西：
// Change This Definition to choose BSP Clock !!! (and "s3c6410.inc")
//#define TARGET_ARM_CLK CLK_66_5MHz //< Sync 66.5:66.5:66.5 HCLKx2=266
//#define TARGET_ARM_CLK CLK_133MHz //< Sync 133:133:66.5 HCLKx2=266
//#define TARGET_ARM_CLK CLK_266MHz //< Sync 266:133:66.5 HCLKx2=266
//#define TARGET_ARM_CLK CLK_400MHz //< Async 400:100:50 HCLKx2=200
//#define TARGET_ARM_CLK CLK_450MHz //< Sync 450:150:37.5 HCLKx2=300
#define TARGET_ARM_CLK CLK_532MHz //< Sync 532:133:66.5 HCLKx2=266, Async is same
//#define TARGET_ARM_CLK CLK_600MHz //< Sync 600:150:75 HCLKx2=300
//#define TARGET_ARM_CLK CLK_666MHz //< Sync 666:133.2:66.6 HCLKx2=266.4, Async 666:133:66.5 HCLKx2=266
//#define TARGET_ARM_CLK CLK_798MHz //< Sync 798:133:66.5 HCLKx2=266
//#define TARGET_ARM_CLK CLK_800MHz //< Sync 800:133.33:33.33 HCLKx2=266.66, ASync 800:133:66.5 HCLKx2=266
//#define TARGET_ARM_CLK CLK_900MHz //< Sync 900:150:75, HCLKx2=300
是不是注释掉不同的 就可以修改用不同的时钟频率跑了呢？
