skyeye模拟的硬件环境，内核里能否修改寄存器？

grantchien

修改2410的寄存器S3C2410_MPLLCON无效， skyeye是不是除了能把硬件跑起来， 就只能在上面跑一些应用了

grantchien

把console_init注掉， 还能打印信息， 这个skyeye的串口到底是怎么工作的呀，这没有仿真好硬件呀？

ksh

There is some register that not simulated. I added MPLLCON write in current source repository, or you can patch your skyeye source according to http://lists.gro.clinux.org/pipe ... -August/001465.html

I had tried to comment console_init. That seems no meesage output except some error message from SkyEye.
