A pc tool reads sys_config1.fex and store all the config in a data
struct and write it to a file which is later put in nanda called
script.bin. script.bin is used in linux drivers to get hardware

Another pc tool reads sys_config1.fex and write important config
(mainly dram para and uart para) to boot0 so boot0  can init dram.
