From 18c70d7222bcea65d08e1ff879d8f69f2705e7ab Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Fri, 14 Sep 2007 14:58:33 +0000 Subject: More range for HT_CHAIN_UNITID_BASE and HT_CHAIN_END_UNITID_BASE. For example: in C51/MCP55 or C51/MCP51 Will allow 1. C51 at 0x10 to 0x14, and MCP at 0 to 4 2. C51 at 1 to 4, and MCP at 7 to 0x0a The reason is c51/mcp51/mcp55 reported unitid is 0x0f (far beyond it needed), and will prevent us from putting them on bus 0. Typical values for c51/mcp55 or c51/mcp51: HT_CHAIN_UNITID_BASE = 0x10 # for C51 HT_CHAIN_END_UNITID_BASE = 0 # for mcp If only have mcp with c51, HT_CHAIN_UNITID_BASE = 0 # for MCP #HT_CHAIN_END_UNITID_BASE = 0 # default value 0x20 Signed-off-by: Yinghai Lu Acked-by: Stefan Reinauer git-svn-id: svn://svn.coreboot.org/coreboot/trunk@2776 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1 --- src/southbridge/nvidia/mcp55/mcp55_enable_rom.c | 2 +- src/southbridge/nvidia/mcp55/mcp55_enable_usbdebug_direct.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) (limited to 'src/southbridge/nvidia/mcp55') diff --git a/src/southbridge/nvidia/mcp55/mcp55_enable_rom.c b/src/southbridge/nvidia/mcp55/mcp55_enable_rom.c index 6a2697537e..f18edb74a3 100644 --- a/src/southbridge/nvidia/mcp55/mcp55_enable_rom.c +++ b/src/southbridge/nvidia/mcp55/mcp55_enable_rom.c @@ -21,7 +21,7 @@ * Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA */ -#if HT_CHAIN_END_UNITID_BASE < HT_CHAIN_UNITID_BASE +#if HT_CHAIN_END_UNITID_BASE != 0x20 #define MCP55_DEVN_BASE HT_CHAIN_END_UNITID_BASE #else #define MCP55_DEVN_BASE HT_CHAIN_UNITID_BASE diff --git a/src/southbridge/nvidia/mcp55/mcp55_enable_usbdebug_direct.c b/src/southbridge/nvidia/mcp55/mcp55_enable_usbdebug_direct.c index c431724c5c..ac4e42ab8d 100644 --- a/src/southbridge/nvidia/mcp55/mcp55_enable_usbdebug_direct.c +++ b/src/southbridge/nvidia/mcp55/mcp55_enable_usbdebug_direct.c @@ -21,7 +21,7 @@ * Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA */ -#if HT_CHAIN_END_UNITID_BASE < HT_CHAIN_UNITID_BASE +#if HT_CHAIN_END_UNITID_BASE != 0x20 #define MCP55_DEVN_BASE HT_CHAIN_END_UNITID_BASE #else #define MCP55_DEVN_BASE HT_CHAIN_UNITID_BASE -- cgit v1.2.3
