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 <patrick@georgi-clan.de> Reviewed-on: http://review.coreboot.org/1887 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org> Reviewed-by: Marc Jones <marcj303@gmail.com>
