Good to hear you succeeded!
FWIW, mine boots v4.17-rc5 fine, using arm64 defconfig.
My firmware is:
BL2: R-Car Gen3 Initial Program Loader(CA57) Rev.1.0.12

I was building with defoncfig and getting a kernel that won't be. Simon's config did the trick. Many thanks!

Please try appending the following to the kernel command line:
earlycon keep_bootcon
FWIW, I'm using:
tftpboot 0x4808 h3-salvator-x/Image
tftpboot 0x49f0 h3-salvator-x/r8a7795-es1-salvator-x.dtb
booti 0x4808 - 0x49f0
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!

Booting Salvator-X ES1 board with upstream kernel
Hi there, I am trying to add support for the CryptoCell security IP in the R-Rcar boards to mainline but I've run into some trouble. I have an R-Car 3rd gen Salvator-X ES1 board. I've been able to boot Linux 4.9 on it from the rareness-bsp tree, using the defconfig and the r8a7795-es1-salvator-x DTB with no problems, so the HW is fine. However, I can't seem to boot an upstream kernel (Linus master or soc-for-v4.17 branch) on it. I just get total silence on the UART after u-boot. Any tips or ideas for me to try?
