I guess you're using Rockchip's BSP 4.4 kernel (or one derived from it like Ayufan's or mrfixit2001's)? I think the Rockchip BSP u-boot (and actually more importantly their binary Trusted Firmware) is probably better matched with Rockchip BSP kernel. The 4.4 kernel is probably making some call to the Rockchip binary firmware to reboot the system, which the open-source ARM Trusted Firmware doesn't interpret properly. All I can say is I have been using this u-boot with 5.x Linux kernels and reboot (with Linux calling TF-A via PSCI to reboot) works successfully.

I'm following Rockchip's default partition layout for SD/MMC, if you have a look at the table on that linked page, it places u-boot at 16384 sectors - it could probably go lower as I don't think the "vendor storage" and "reserved" space is used by the fully-open-source boot loader and firmware, but I wanted to stick with what was "standard" to avoid confusion.
