Sure, here it is:
earlycon=msm_serial_dm,0x78b3000 console=ttyS0,115200n8
You also need to force the cmdline.
This address is UART5, check what UART you use first

Unfortunately there is not more output as before even with earlycon in the commandline.
UART5 should be right it's the same as in u-boot.
I tried the elf image and again the initramfs.itb

Since we really need to test the bootup... and if someone has lots of time, what could be quicker is test older kernel version and remove any patch that doesn't apply to the newer kernel (starting with the newer) (both generic and ipq807x) i mean it's 4 kernel version not that much ahahha

I had a chance to test 5.10-rc1 on the IPQ6018 CP01-C1 board, and it has the same issue.
Simply no output after Jumping to AARCH64 kernel via monitor
Ok, this now makes no sense.
Its gotta be something upstream.
Update, I fixed the earlycon address and this is a clue:

Ok, it points to this:
Ok, so reducing the load and entry address for uImage by 0x80000 solved that warning, unfortunately it still hangs after PSCI.
I suspect the same things is bugging IPQ807x as well as everybody using the old load and entry addresses

Haha, it was the damn text offset in load address.
Upon changing load and entry addresses earlycon now magically works.
Ok, it still panics, but we are making progress.

0000a0 looks like a error pointer treated as pointer...
Most likely, there have been similar stuff in Qualcomm clk drivers.
It should be easy to find with stack trace decoding, I am glad that it boots.
Now we can done some good stuff.

so the problem was in a wrong load address ?
Yes, ARM64 before 5.8 was using TEXT_OFFSET of 0x80000.
Since this was a legacy thing carried over from ARM and never intended to be used, it was changed to 0x0 in 5.8 and a warning like I saw on IPQ6018 which at least printed something was added.
Then in 5.10 TEXT_OFFSET was dropped completely.
The issue is that everybody simply added the 0x80000 to uImage load and entry addresses, and since OpenWrt kernel config does not enable relocation support by default kernel would not even start.
If we had enabled the relocation it would at least start enough to print the warning when using earlycon.
Subtracting 0x80000 from the load and start addresses resolves that, I have pushed that to my branch.
Anyway, I am going to sleep.
Should have some time tommorow to try and find where is it panicking.

Sorry for the stupid question... since they dropped TEXT_OFFSET now this needs to be fixed for all the target
Well, it only affects ARM64 aka AARCH64 targets, ARM is not affected as it required TEXT_OFFSET which is platform specific.
So, yes this will need to be corrected for all 64bit ARM targets in OpenWrt

It boots on the RAX120 as well without a panic, but later stucks at random: 3 urandom warning(s) missed due to ratelimiting

Its missing the base files script to drop you into shell.
Its weird that it boots on RAX120

Nice work, I would never have found that myself 
Possible its some difference between IPQ8074 V1 and V2 on the RAX120 (QSDK had sone changes in GCC drivers I think)
1 Like
Could be but I would think that V2 would boot rather than V1 since that's the only one supported upstream.

@Ansuel Do you maybe have time for some of your magic?
I am looking at the clock issue, but the stack trace does not really point to a specific issue as the clock driver gets probed, etc, but it fails on clk_core_get_parent_by_index.
That's not really helpful as that one gets called a lot of times
