I have put this in OpenWrt:

https://dev.openwrt.org/browser/trunk/package/boot/uboot-envtools/patches/110-add-support-for-MTD_ABSENT.patch
https://dev.openwrt.org/browser/trunk/package/boot/uboot-envtools/patches/115-writing-environment-for-mtd-devices.patch

With those two you will be able to use fw_{printenv,setenv} on MMC
devices.
