K8 + 2.4.21 + Tyan S2880

Eric,

My boss has said that I can release the source code to you.

Please find out the patch I made. Make the diff to today's tree.

I didn't test RON new script and still use the old scripts tools.

I strip out the LSI scsi support, because I don't know if there is any
license problem, and I have referred to their documents and may need put
their FW in the ROM.

It's greater you add ops->enable function that make it easy to handle
special device. To some device if it is not gotten magic code, it will not
get the resource allocate to it. Before that I have to do it in init
function and re-allocate the resource to it again. Please refer to my old
amd8131_ioapic.c in southbridge/amd8111. Also you init the io_base, upper16
reg, otherwise the device in PCIX will not got io port allocated to them,
and will not work. 

I have tested Stefan's the code about coherent_ht.c, and add some hardcode
to it.
coherent_ht.o.c is the original one. Coherent_ht.1.c is total hardcode one.
coherent_ht.c and coherent_ht.2.c are modified with some hardcode ones.

raminit.c and raminit.1.c are till the hardcode one, and I have tried to use
the configurable one, but auto.c can not be compiled, it is too big and used
up REG?
The old one has been renamed to raminit.o.c. 

To start other cpus, in auto.c  We must enable apic and make sure all
apic_id is right. Please refer to mainboard/tyan/s2880/auto.c boot_cpu
function.

Again, thank you all to answer my questions to help Tyan s2880 work with
LinuxBIOS.

Regards

Yinghai Lu
