Please describe what ATF/OP-TEE initialization has done
when booting into uboot.

I think SKIP_LOWLEVEL_INIT is mostly for lowlevel_init,
not arch_cpu_init.

init_aips/init_csu/isolate_resources/init_snvs might be
done in your ATF, I am not sure, but imx_enet_mdio_fixup,
mxs_dma_init, imx_gpcv2_init, are these also done in ATF?

Regards,
Peng.
