The code can run on the Mahogany board, which is one of sample boards
made by AMD. Its major features are:
CPU:
* AMD AM2+
* AMD Athlon 64 x2
* AMD Athlon 64 FX
* AMD Athlon 64
* AMD Sempron CPUs
System Chipset:
* RS780E
* SB700
On Board Chipset:
* BIOS - SPI
* Azalia CODEC - Realtek ALC888
* LPC SuperIO - ITE8718F(GX).
* LAN - REALTEK 8111C
* TPM - SLB9635TT1.2
Main Memory:
* DDR II * 4 (Max 4GB)
Expansion Slots:
* PCI Express X16 slot*2 (PCI-E X8 Bus)
* PCI Express X4 Slot*1
Intersil PWM:
* Controller - Intersil 6323
Note:
1. The only difference to mahogany is the CPU is changed to K8 family 10.
2. The main structure of the code is based on
serengeti_cheetah_fam10. I am a rookie to fam10. I am still
confused about CONFIG_HT_CHAIN_UNITID_BASE and
CONFIG_HT_CHAIN_END_UNITID_BASE. I set them as the way dbm690t
does. And I have to modify the some fam10 code (see the patch
ht_chain_unitid_base.patch). I dont know how to solve this. Please
help.
Updated findings: In h3finit.c, the code goes the AMD_CB_ManualBUIDSwapList().
The swaplist is {0x00, 0x00, 0xFF, 0x00, 0xFF}. I am trying to find the meaning
of the list. The amdht wrapper needs to modify definitely.
3. With fam10 processor, the HT link can work in HT3.
4. The ACPI _PSS table is set staticly. The auto configuaration
process doesnt seem to work correctly.
5. Currently the fam10 code in coreboot doesn't support DDR3. If you
happen to get a board with DDR3 and you don't have the patience to wait,
please find another board with DDR2.
6. It will take "Uncompressing image to RAM" about 1 minute. I know it is a
issue for a long time. I disable the compressing currently. When the problem
is fixed, we can re-enable it.
