Can you attach your boot.init file (the source of boot.scr)?

By the size of DTB you can see that different DTB is loaded. I assume
you tried to boot the same kernel, then it could mean that boardname
was used instead of board_name to choose DTB. Suspicious is that
kernel size also differs... so maybe you booted something else? As
usual debugging practice, reduce number of unknown factors. Do not
change kernel and U-Boot at the same time.

Also, you can try reverting commit e6b1467081d3 ("arm: exynos: Remove
duplicated "boardname" env setting") and see if it helps. Or just try
to bisect around changes coming from u-boot samsung tree. Try booting
v2019.01 and paste the results as well.

Best regards,
Krzysztof
