BCM63168VKFEBG nand support

Hello, I'm building openwrt for Sagemcom F@st 5350, this router has NAND and SPI memory. I build openwrt for it based on Sky sr102 dts.
It is working but when I added to dts NAND it's not detecting it. I get following error on serial:

[    0.823054] nand: No NAND device found
[    0.827995] nand: No NAND device found

Here is my dts: https://pastebin.com/yPFNb24G

In modem stock firmware I can get a bit of information about NAND:

NAND chip is W29N01HVS.

Does anybody know what I need to change to make it working?

Thanks for help.

search the forum for W29N01HVS, there's a couple of threads mentioning it, perhaps you can draw some conclusions by looking at those devices.

I already seen them, but they are about routers with MediaTek.
Configuration of NAND in dts from this MediaTek routers looks normal.
I'm not sure why it's not working.
Is it problem specific to this router or with broadcom?

Hello. Did you manage to get OpenWRT working on 5350? If yes, could you provide a ready-to-deploy version of it?

@tpiechowiak
I got it to boot openwrt from external SPI memory MX25L12845, there are empty pads for it on bottom of pcb.
Unfortunately I haven't found any way to detect NAND.
Do you have the same router, do you done any testing with it?
