     I finally can boot it with the rock_defconfig. But the way to 
package the tpl spl u-boot a little different.

     cat ${DIR}/out/tpl/u-boot-tpl.bin > tplspl.bin
     truncate -s 1020 tplspl.bin
    sed -i "/^/{1s/^/RK31/}" tplspl.bin
    cat ${DIR}/out/spl/u-boot-spl.bin > spl.bin
    truncate -s %2048 spl.bin
    cat spl.bin >> tplspl.bin

    Then the tplspl.bin + u-boot.bin should package by 
boot_merger(tplsplb.in for FLashData, u-boot.bin for FlashBoot) from 
rockchip downstream u-boot repo:
    ./tools/boot_merger ./tools/rk_tools/RKBOOT/RK310BMINIALL.ini

    download to emmc by "upgrade_tool ul" command. According to our 
bootrom code author, the rk31(maybe include rk30) bootrom has a 
limitation that the idbblock
couldn't accessed by upgrade_tool wl command.
