Eric,
After update raminit.c now MB can boot into linuxbios.
The s2880 has six memory slot: 4 for CPU0 ,and 2 for CPU 1. I can only init 4 for CPU0. I have tried: #cp raminit.c raminit1.c and rename all function in the raminit1.c to xxxxx_1 copy genric_sdram.c to generic_sdram1.c in the sdram dir. Also add the calling function in auto1.c. and can not pass the test.
Any advice on init RAM on second cpu northbridge?
I have try to enable SMP support in LinuxBIOS and can not compile it through. Miss severl function. (Spin for Only CPU and start second CPU.S). When do you plan to add it? Or can tell me your idea and I can add it right now.
Regards
Yinghai Lu

Eric,
After update raminit.c now MB can boot into linuxbios.
The s2880 has six memory slot: 4 for CPU0 ,and 2 for CPU 1. I can only init 4 for CPU0. I have tried: #cp raminit.c raminit1.c and rename all function in the raminit1.c to xxxxx_1 copy genric_sdram.c to generic_sdram1.c in the sdram dir. Also add the calling function in auto1.c. and can not pass the test.
I am not certain which test is failing.
The only test that really matters is memtest86. The builtin test of LinuxBIOS are just enough to see if the memory has been seriously misconfigured.
Any advice on init RAM on second cpu northbridge?
That is going to be a challenge. I am pretty certain we can reuse much of the code. But it needs to get cleaned up first.
I am about a day or two out before I am satisfied with the memory initialization code I am working on. I was starting to make progress and then I got distracted by the lack of support for structures in memory by romcc, so I have just finished implementing that. They are needed for some lookup tables based on memory speed.
I have try to enable SMP support in LinuxBIOS and can not compile it through. Miss severl function. (Spin for Only CPU and start second CPU.S). When do you plan to add it? Or can tell me your idea and I can add it right now.
I don't think it is going to change much from the freebios tree, although there is a little of that in my wish list. If there are some missing functions it should be possible to get them out of the freebios tree. And a patch doing that would be appreciated.
If I read your boot log properly you have enabled ecc support for you memory. The memory timings you are using are not solid, and you are getting a machine check because the memory is not stable.
Eric
