Override full environment?

I want something similar to this:

load mmc 1:2 0x80F80000 /boot/am335x-boneblack.dtb
load mmc 1:2 0x80007fc0 /boot/uImage
setenv bootargs console=ttyO0,115200n8 ${optargs} root=/dev/mmcblk0p2 ro rootfstype=ext4 rootwait
bootm 0x80007fc0 - 0x80F80000

Modified it to:

load mmc 0:1 0x80F80000 am335x-boneblack.dtb
load mmc 0:1 0x80007fc0 zImage
setenv bootargs console=ttyS0,115200n8 root=/dev/mmcblk0p2 ro rootfstype=ext4 rootwait
bootz 0x80007fc0 - 0x80F80000

Which boots the kernel

so how to overwrite the environment?
