uboot step suggestion

[sam_siu]

For the u-boot step 1, I would add the following for consistence:

1. $ export ARCH=arm64
2. $ export CROSS_COMPILE=aarch64-linux-gnu-

I run all the steps in my build machine and it works. So I approve this version with the above modification.

Hello Sam Siu,

Do you mean the procedure to build u-boot?

Please refer to the following procedure

$ source /opt/fsl-qoriq/2.6/environment-setup-aarch64-fsl-linux

$ make CROSS_COMPILE=aarch64-fsl-linux- ls2088ardb_qspi_defconfig

$ make -j 4 CROSS_COMPILE=aarch64-fsl-linux- all

Thanks,

Yiping
