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.
