Can someone explain what RAMINIT_SYSINFO configuration option does? I thought I understood, but I don't.

Hi Oskar,
RAMINIT_SYSINFO is the config option to create the AMD sysinfo structure in CAR above the stack. This is a way to get global data in the romstage (heap like without any management). The space for the data structure is allocated by the DCACHE_RAM_GLOBAL_VAR_SIZE config and the pointer is setup in cache_as_ram_main.
