From bbc880eee702fc175d4a3c3e87b682c26c38f940 Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Tue, 20 Nov 2012 18:20:56 +0100 Subject: amdk8/amdfam10: Use CAR_GLOBAL for sysinfo This gets rid of the somewhat unstructured placement of AMD's sysinfo structure in CAR. We used to carve out some CAR space using a Kconfig variable, and then put sysinfo there manually (by "virtue" of pointer magic). Now it's a variable with the CAR_GLOBAL qualifier, and build system magic. For this, the following steps were done (but must happen together since the intermediates won't build): - Add new CAR_GLOBAL sysinfo_car - point all sysinfo pointers to sysinfo_car instead of GLOBAL_VAR - remove DCACHE_RAM_GLOBAL_VAR_SIZE - from CAR setup (no need to reserve the space) - commented out code (that was commented out for years) - only copy sizeof(sysinfo) into RAM after ram init, where before it copied the whole GLOBAL_VAR area. - from Kconfig Change-Id: I3cbcccd883ca6751326c8e32afde2eb0c91229ed Signed-off-by: Patrick Georgi Reviewed-on: http://review.coreboot.org/1887 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer Reviewed-by: Marc Jones --- src/northbridge/amd/amdfam10/amdfam10.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'src/northbridge/amd/amdfam10/amdfam10.h') diff --git a/src/northbridge/amd/amdfam10/amdfam10.h b/src/northbridge/amd/amdfam10/amdfam10.h index 712c98638e..4c06463ab9 100644 --- a/src/northbridge/amd/amdfam10/amdfam10.h +++ b/src/northbridge/amd/amdfam10/amdfam10.h @@ -1098,6 +1098,10 @@ struct sys_info { } __attribute__((packed)); +#ifdef __PRE_RAM__ +extern struct sys_info sysinfo_car; +#endif + #ifndef __PRE_RAM__ device_t get_node_pci(u32 nodeid, u32 fn); #endif -- cgit v1.2.3
