Re: [coreboot] [PATCH] exit from self-refresh on AMD K8 CPUs (pre revF)

[Fengwei Zhang]

Hi Rudolf,

I have tested S3 on m2v-mx_se. It works perfectly. Except following 
situation.

As you know, there are two Dimms in m2v board. if I put 1 memory module 
on it, S3 would work perfectly. If I put 2 memory module on both two 
dimms. The coreboot cannot boot. it would stop at post_cache_as_ram() 
function.

In the beginning, you read resume_backup_memory from 
backup_resume()function. resume_backup_memory should be 0 when we booting.
However, it will change after calling disable_cache_as_ram_bsp() 
function, and resume_backup_memory == 0xffffffff.

Then it will get into memcopy() function, which would stop booting.

If I am guessing right, you just put one memory module in your board for 
your testing, right?

Best,
Fengwei
