Well..
I think I managed to build out a x86_64 er50 kernel and loaded it onto a mips_24kc device.. I can't imagine why it won't work..
When I originally setup the external kernel, I forgot (because I didn't know at the time) to include an ARCH=mips to my make menuconfig, so, it "defaulted" to the host arch, and then tried to apply the ubnt_er_e50_defconfig in a x86_64 environment ...
I'm trying to build out with it set to actually be mips.. and I'll report back.
Didn't change.. Still getting the just stopping at Booting the kernel.
I've noticed a few things.. The .bin size is very small (4mb). That's the defined kernel size in my device defines.. It's like the squashfs isn't part of that initramfs bin..
The size of the file under my main branch 5.10 build is 15mb...
Ideas?
the squash shouldn't affect whether or not you get a boot log.
it does affect whether you get a full boot after the kernel initialisation, though.
i would check your DTS files again to be sure, and i would use the openwrt ones instead of making changes to the ones you have.
this does smell like an issue related to the DTS since your configuration looks correct. the mt7621 does not really have issues like this. i would also check and be sure your bootargs variable in u-boot. it may be that the ttyS1,57600n8 is coming from your bootloader and overriding the ttyS0,57600n8 in your kernel configuraiton.
I'm going to ditch the 19.07 and go for my main branch build. I can get that build system to build a bootable image for OpenWrt's 5.10, so I'll try to build out the 4.14 for it and see what happens.
from what i can see, most of the mt7621 stuff is now on 5.10.
from what i also saw, your config build file was spitting out (what seems to be) 5.10 build settings for a 4.14 kernel. this may be part of the problem.
just try a 5.10 build. it shouldn't hurt. maybe driver compatibility issues will arise for edgerouter stuff, but at least you'll see a boot log to reach that conclusion.
I've got a 5.10 build and only partially works (Switch Setup for Edgerouter 10X (RTL8367RB))
The issue is that the 5.x drivers for the RTL8367RB switch AND the MT7621 (which is now DSA) aren't the proper ones that are needed to make the ER10x actually work properly. My ultimate goal is to rip out the drivers from the 4.14 kernel and try to get them into the ramips target.
cool, that makes sense.
i think the issue really is the DTS files. i know i haven't been able to keep my mt721.dtsi up to date with the latest in the openwrt tree since they've made a few structural changes (DSA being one, as you noted) that prevent me from doing so.
they also added things like a 'gmac' node to the ethernet driver and such, which are not compatible with the old 4.14 driver that has hardware nat support.
these are just some things i have observed.
nod I'm not actually using the dts/dtsi files from OpenWrt, but a flattened from overlay file that I make available to the build system. I was looking to use 19.07 because I know 4.14 would, in theory, be no issue. Either way, I keep both repos local, so will test until I find something 
I'll post my dts/dtsi files if you're interested in looking
to be honest, if you can't get a serial output, i think it's either your cmdline arguments aren't being passed. but since you have a 5.10 build partially working that rules out the u-boot arguments of ttys1 being a problem.
since you added the console argument to the dts i can't see anythign else being an issue. it sucks we can't even see the first few lines of boot 
I see the same bootargs being passed from uboot in the 5.10, so OpenWrt is probably injecting them elsewhere We will see:)

really appreciate your persistence.
it's what you need to make a name for yourself in this game.
you're already doing it. good job
@grommish are you okay bud? hopefully you didn't give up.
maybe you can find a github with an older openwrt tree. that should work right?
I didn't give up I'm too stubborn for that, but I've had other things I've had to focus on.
I was able to make the ER10x work with the already-baked in ralink drivers in the 5.10 kernel. With the exception of the Eth5 port. In looking at the rtl8367rb datasheet, there are ports 0-4 + cpu + e0 and e1 ports. The mt7621 has gmac1 available. I'm wondering if it couldn't be connected that way shrug
that's definitely to do with the changes to the DTS file in 5.x
i am a fan of 4.14 myself for this reason. i didn't like the addition of the "gmac1" nodes and things like that. DSA is all the rage these days apparently.
i found the openwrt mediatek driver for 4.14 to be 'better' too, in the sense it had hardware nat using flow_offload (for wired devices only). maybe they've incorporated that into the newer kernels now.
I've got the 4.14 kerne from Ubiquiti, but it doesn't like building or booting once built
There was a split somewhere between 4.14 and 5.10 in the kernel drivers and where things live. The MediaTek stuff moved to ralink, but not all of it. So the DTS issue could certainly just be a missing driver issue.
It doesn't help that I'm not overly familar with the dts format itself 
it's annoying for sure.
i would look at the driver you have in the 4.14 dir. if it references 'gmac' or stuff like that, you're using the wrong one.
paste some of the source of your 4.14 driver and we can see if that's part of the problem.
the strangest thing is you're not getting a terminal printout, and i want to say that has to do with something in the kernel. wanna paste your full 4.14 kernel configuration?
The &gmac1 is part of the mt7621 device tree. That's the primary board, the rtl is an add-on.
So, if I could enable the gmac1 port on the mt7621 and send the ephy (e0/e1) from the rtl to it as the rgmii connection, it would eliminate the need to use port@5 on the switch0 mt7621 define, which is where I think the issue is with eth5.
This is the dts I'm using.

so right now your preference, if i understand you correctly, is to get a 5.10 kernel running with the older ethernet driver, correct?
could you elaborate as to what is missing in the driver for the device to get full acceleration? what is the older driver that does give full acceleration? what is that dts configuration?
i hate the dts setup for DSA, but it is what it is. maybe we can work with what the GPL code gives and find a solution.
i assume the dts+mtk_eth_soc from 4.14 do give full acceleration, but DSA is disabled?
Ubiquiti doesn't use DSA in the 4.14 kernel, it explicitly calls CONFIG_SWCONFIG=y in the arch/mips/configs/ubnt_er_e50_defconfig, which is what I used as my starting point.
However, the mt7621 is DSA now, and afaik, the rtl8367rb is not.
