This is intended to be used where the boot firmware boots on the SoC's
boot device (emmc in the case of the Gateworks Newport octeontx board)
but the OpenWrt OS itself (bootfs/rootfs) are on USB. The user may
have for example a backup or alternate OS on different devices (USB,
SATA, microSD, etc). It looks to me like many targets enable this and
I believe it was enabled in a previous kernel version but I find its
something that often gets disabled likely be accident when bumping
kernels.
