Jumping to U-Boot
SPL malloc() used 0x0 bytes (0 KB)
loaded - jumping to U-Boot...
image entry point: 0x4a000000
It looks like SPL loads 0x0 bytes of u-boot and runs it! Hmm,
It appears not zero size but rather zero-filled image is retrieved for
some reason, without I/O error, but still erroneously. Uhhh, apparently
there is no reasonably way to check if raw u-boot body image is valid or
not so SPL simply jumps there, and of course nothing usefull happens.
Now just need to see why the image is actually zeroed.
Besides, I've got a feeling that using a raw u-boot body, as per default
setup, is not really a good choice, since the diagnostics is essentially
missing and it also means an emergency second copy will not necessarily
help if the main file was e.g. erroneously overwritten.
Thank you!

interesting. Its a good start already. Now just need to insert some more
debugging messages...
Thank you!

Background: I'm trying to perform direct nand install on an A20
olinuxino board. That is, dismissing messy boot0 and boot1 in nand.
Currently, I've succeeded to get a good greeting from u-boot SPL,
declaring that it is going to proceed to boot from nand, but then all
stops forever:
U-Boot SPL 2019.01-rc2 (Dec 22 2018 - 22:15:16 +0300)
CPU: 912000000Hz, AXI/AHB/APB: 3/2/2
DRAM: 1024 MiB
Trying to boot from NAND
I'd like to try to find the reason for this and certainly having all
those debug messages could help somewhat.
Thank you!
Regards,
Nikolai
