https://review.coreboot.org/c/coreboot/+/34976/4/src/cpu/intel/car/romstage.... PS4, Line 35: size = MIN(size, stack_size);
looking at the linker script _car_stack_size is the same as CONFIG_DCACHE_BSP_STACK_SIZE. […]
There are 2 definitions of _car_stack_{start,end} in car.ld.
It's there for cases where CONFIG_DCACHE_BSP_STACK_SIZE is not defined (platforms without C_ENVIRONMENT_BOOTBLOCK).
