If CONFIG_USE_INIT == 0, the cache_as_ram_auto.c will be compiled to
auto.inc. ---> part of crt0.s---> part of linuxbios_rom
If CONFIG_USE_INIF == 1, the cache_as_ram_auto.c will be compiled to
auto.o and be linked with memcpy.o....and auto.o and memcpy.o --->
init.o
And init.o ---> part of linuxbios_rom...

That's something I try to figure out. If DCACHE_RAM needs USE_INIT,
why we still have
#if CONFIG_USE_INIT == 0
#include "lib/memcpy.c"
#endif
in the src/mainboard/tyan/s2895/cache_as_ram_auto.c ?
