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/acpi.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/northbridge/amd/amdfam10/acpi.c') diff --git a/src/northbridge/amd/amdfam10/acpi.c b/src/northbridge/amd/amdfam10/acpi.c index 87c2d8c0e9..14efa9792e 100644 --- a/src/northbridge/amd/amdfam10/acpi.c +++ b/src/northbridge/amd/amdfam10/acpi.c @@ -134,7 +134,7 @@ unsigned long acpi_fill_slit(unsigned long current) /* fill the first 8 byte with that num */ /* fill the next num*num byte with distance, local is 10, 1 hop mean 20, and 2 hop with 30.... */ - struct sys_info *sysinfox = (struct sys_info *)((CONFIG_RAMTOP) - CONFIG_DCACHE_RAM_GLOBAL_VAR_SIZE); + struct sys_info *sysinfox = (struct sys_info *)((CONFIG_RAMTOP) - sizeof(*sysinfox)); u8 *ln = sysinfox->ln; -- cgit v1.2.3
