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/mainboard/tyan/s2912/Kconfig | 4 ---- src/mainboard/tyan/s2912/ap_romstage.c | 4 ++-- src/mainboard/tyan/s2912/romstage.c | 3 +-- src/mainboard/tyan/s2912_fam10/Kconfig | 4 ---- src/mainboard/tyan/s2912_fam10/romstage.c | 2 +- 5 files changed, 4 insertions(+), 13 deletions(-) (limited to 'src/mainboard/tyan') diff --git a/src/mainboard/tyan/s2912/Kconfig b/src/mainboard/tyan/s2912/Kconfig index 67b89d1c4b..f653478756 100644 --- a/src/mainboard/tyan/s2912/Kconfig +++ b/src/mainboard/tyan/s2912/Kconfig @@ -33,10 +33,6 @@ config DCACHE_RAM_SIZE hex default 0x08000 -config DCACHE_RAM_GLOBAL_VAR_SIZE - hex - default 0x01000 - config APIC_ID_OFFSET hex default 0x10 diff --git a/src/mainboard/tyan/s2912/ap_romstage.c b/src/mainboard/tyan/s2912/ap_romstage.c index fc7df821f2..e48d899829 100644 --- a/src/mainboard/tyan/s2912/ap_romstage.c +++ b/src/mainboard/tyan/s2912/ap_romstage.c @@ -56,8 +56,8 @@ void hardwaremain(int ret_addr) { - struct sys_info *sysinfo = (CONFIG_DCACHE_RAM_BASE + CONFIG_DCACHE_RAM_SIZE - CONFIG_DCACHE_RAM_GLOBAL_VAR_SIZE); // in CACHE - struct sys_info *sysinfox = ((CONFIG_RAMTOP) - CONFIG_DCACHE_RAM_GLOBAL_VAR_SIZE); // in RAM + struct sys_info *sysinfo = &sysinfo_car; // in CACHE + struct sys_info *sysinfox = ((CONFIG_RAMTOP) - sizeof(*sysinfox)); // in RAM struct node_core_id id; diff --git a/src/mainboard/tyan/s2912/romstage.c b/src/mainboard/tyan/s2912/romstage.c index fc5d65966d..2423117c5e 100644 --- a/src/mainboard/tyan/s2912/romstage.c +++ b/src/mainboard/tyan/s2912/romstage.c @@ -112,8 +112,7 @@ void cache_as_ram_main(unsigned long bist, unsigned long cpu_init_detectedx) DIMM5, DIMM7, 0, 0, }; - struct sys_info *sysinfo = (struct sys_info *)(CONFIG_DCACHE_RAM_BASE - + CONFIG_DCACHE_RAM_SIZE - CONFIG_DCACHE_RAM_GLOBAL_VAR_SIZE); + struct sys_info *sysinfo = &sysinfo_car; int needs_reset = 0; unsigned bsp_apicid = 0; diff --git a/src/mainboard/tyan/s2912_fam10/Kconfig b/src/mainboard/tyan/s2912_fam10/Kconfig index 9a38836e6f..085148fcd3 100644 --- a/src/mainboard/tyan/s2912_fam10/Kconfig +++ b/src/mainboard/tyan/s2912_fam10/Kconfig @@ -33,10 +33,6 @@ config DCACHE_RAM_SIZE hex default 0x0c000 -config DCACHE_RAM_GLOBAL_VAR_SIZE - hex - default 0x04000 - config APIC_ID_OFFSET hex default 0 diff --git a/src/mainboard/tyan/s2912_fam10/romstage.c b/src/mainboard/tyan/s2912_fam10/romstage.c index 16d3c472bd..bc01aeaa8e 100644 --- a/src/mainboard/tyan/s2912_fam10/romstage.c +++ b/src/mainboard/tyan/s2912_fam10/romstage.c @@ -113,7 +113,7 @@ static const u8 spd_addr[] = { void cache_as_ram_main(unsigned long bist, unsigned long cpu_init_detectedx) { - struct sys_info *sysinfo = (struct sys_info *)(CONFIG_DCACHE_RAM_BASE + CONFIG_DCACHE_RAM_SIZE - CONFIG_DCACHE_RAM_GLOBAL_VAR_SIZE); + struct sys_info *sysinfo = &sysinfo_car; u32 bsp_apicid = 0, val, wants_reset; msr_t msr; -- cgit v1.2.3
