ENGR00321260-2 iMX6:Android: Append the "androidboot.serialno" to bootargs
Android supports to two ways to pass serialno:
1. ATAG_SERIAL
2. "androidboot.serialno=" argument in boot commandline.
Since we support the DTB for android, so the ATAGS can't work. We have to choose
the second way.
This patch only applys the bootargs in bootimg, while the bootargs saved in u-boot
env variables won't have this argument appended.
