NanoPC-T4 PCIe: fails to detect M.2 PCIe-SATA card

[redfish]

NanoPC-T4 not detecting M.2 PCIe-SATA card at all.

Card:
M.2 B+M Key 22x42 PCIe To 2 Port SATA III RAID Adapter Card - SI-ADA40126

Same error with and without card inserted.

Same with 4.4.179, 4.4.143, tried with 4.4 shipped with Lubuntu image. Built from friendlyarm repo on github, tried kernel-rockchip repo from Rockchip. Same behavior. Did not edit device tree.

For completely unrelated reason (mmc partitions), I had to add a patch to the mainline kernel. Attaching here. Also, copied tools to pack .img image from kernel-rockchip repo from FriendlyARM.

Device tree from mainline, but rename the binary, because bootloader looks for a particular name in the resource.img image.

Redfish thanks for your hard work. Im running the T4 with a 500G NVME. It's not recognized whatsoever. Using FriendlyCore 18.04. Fully apt-get update/upgraded

uname -a
Linux NanoPC-T4 4.4.179 #1 SMP Tue Sep 15 15:56:24 CST 2020 aarch64 aarch64 aarch64 GNU/Linux

Will your patch also work for .179?
