MT6737模块编译方法

前提是提前编译整个系统。

Preloader模块：

rm -rf out/target/product/len6737t_66_sh_n/obj/PRELOADER_OBJ 

编译命令变为：（不再是PDF文档的命令）
mmm vendor/mediatek/proprietary/bootable/bootloader/preloader:pl

编译成功:
len6737t_66_sh_n preloader load
/media/zuoyi/D02497132496FC22/MT6737VCA/XY3701_N0/out/target/product/len6737t_66_sh_n/obj/PRELOADER_OBJ/bin/preloader_len6737t_66_sh_n_LINKED.bin built at
