Compiling Uboot error for IMX8MP EVK

[Harris]

Dears,

I download the latest Uboot source code from https://github.com/Freescale/u-boot-fslc.

My target board is IMX8MP EVK. I use this config mx8mp_evk_defconfig for my Uboot compiling.

The Ubuntu 20.4 is my host system.

I run following commands to compile my uboot.

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- distclean
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- imx8mp_evk_defconfig
make V=1 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j2

Following errors report was present to me:

Would you please help to check and give some comments on my issues. Thank you  so much.

Which version BSP are you using?https://www.nxp.com/design/software/embedded-software/i-mx-software/embedded-linux-for-i-mx-applicat...

Dear,

Yes, I have not setup the BSP for my compiling action.

Thanks for your time.
