Please try appending the following to the kernel command line:
earlycon keep_bootcon
FWIW, I'm using:
tftpboot 0x48080000 h3-salvator-x/Image
tftpboot 0x49f00000 h3-salvator-x/r8a7795-es1-salvator-x.dtb
booti 0x48080000 - 0x49f00000
Which firmware revision do you have? It may be too old to boot moden
(large) kernel images. Check the first line of BL2 output.
Which config are you using? Please try renesas_defconfig from Simon's
repository.
Good luck!
Gr{oetje,eeting}s,
