Any doc or support I could find for build a lightweight UFS driver for hikey960 running fuchsia

Hi,
I got a Hikey960 running as a smart TV box and I want to try with the new fuchsia.

Fuchsia support hikey960 as it’s target , but seems it’s lacking of doc to make it hard to step on. The UFS maybe the first step to run a full Fuchsia (HDMI and GPU also needed but without UFS support , even not able to flash image from zedboot)

Hisi has open sourced it UFS driver together work with Linaro people to the Kernel mainline

https://github.com/torvalds/linux/commit/8111b5e334861c4cd12e49e151e7e2f0e617d46a#diff-b89301a143b4ea4f72e62372fc9d8a8b

but the SCSI is heavy , since the bootloader already support the UFS (could flash image and UFS should be OK in bootloader), any doc or support I could find for build a lightweight UFS driver for hikey960 running fuchsia?

Thanks
