I got the same device last Weekend and planned to add support for this
device during the next days. Glad to see that most of the work is
already done.
Find my remarks in-line.

I'll give it a try. Lately, I worked a lot with u-boot, so I'm
confident that it shouldn't be that problem.
But I need to identify the boot_sel pins first. I have looked at it
only briefly and was only able to identify one of the boot_sel pins:
R77. Unfortunately this pin alone doesn't switch the SoC to UART mode.
Did you found already the other pins?

Please add the real layout here and use proper names for the partitions!

Assuming you're using the brnboot recovery to flash the firmware, this
wont work. brnboot recovery writes alternating to both partitions and
stores the current active one in the Primary Setting partition
(0x80000). Which could results in a situation that the kernel is
stored (and booted) at 0x90000 but the userland + kmods are loaded
from 0x440000. This could lead to a lot of errors and your additional
flash space for volatile data isn't available as well. My patch to use
the current active partition as firmware partition was merged lately
to OpenWrt. Have a look at the VGV7510KW22BRN.dts for reference.
As you already noticed, OpenWrt isn't really usable on devices with a
firmware partition <= 4MB. I would even say, that such are not longer
supported. But that is something the core devs need to decide.
Anyway, I would suggest to focus on u-boot + a custom partition layout
to have enough space for luci and so on.
