From 584ab84e92a4db3b96c253bb559d64a8f82cf367 Mon Sep 17 00:00:00 2001 From: Zheng Bao Date: Tue, 16 Mar 2010 01:53:10 +0000 Subject: 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.
