This helps

However, something is going wrong.

That is very odd. Usually earlycon works. The only case I've found where it was unintuitively broken was when U-Boot ran in EL3, but I assume you do have ATF running somewhere, right?
It is supposed to be so.
What you can still try is to recover the kernel log from RAM. For that, boot up the system, then reset (don't power cycle, use the reset button if available, otherwise use the reset line on the jtag port if available). After reset, you should get back to U-Boot. There, run "bdinfo" to find out the base offset of RAM.
What is the offset here?
=> bdinfo arch_number = 0x00000000 boot_params = 0x00000000 DRAM bank = 0x00000000 -> start = 0x00200000
This is the offset. It does sound quite weird though, so don't be surprised if things don't work :).
