From what I can read/understand: - is mmcblk0p2 the rootfs? If so: this partition should get mounted at kernel boot using the "root=..." boot arg. This, in turn, is set by "Das uboot" bootloader. I guess all the glory details can be found in the u-boot-zynq-uenv.bb recipe or similar. - if mmcblk0p2 is not the rootfs, this must be mounted somewhere. A casual place to look at would be /etc/fstab. Is there a /etc/fstab available on your system?
