I discovered the problem.. I'm using Buildroot with the
qemu_aarch64_defconfig and I needed to add these Linux kernel config
options:

CONFIG_MTD=y
CONFIG_MTD_CFI=y
CONFIG_MTD_OF_PARTS=y
CONFIG_MTD_CFI=y
CONFIG_MTD_CFI_INTELEXT=y
CONFIG_MTD_CFI_UTIL=y
CONFIG_MTD_PHYSMAP=y
CONFIG_MTD_PHYSMAP_OF=y

I can successfully run barebox-state on the target, dump, and set
state variables. I'll submit a patch to Buildroot.
