Subject: h8300 for edosk2674 device

Hi,

the attached kernel config errors out with:
/usr/bin/make -f ./scripts/Makefile.build obj=arch/h8300/boot
arch/h8300/boot/uImage.bin
  /home/wbx/h8300/toolchain_hitachi-edosk2674_uclibc-ng/usr/bin/h8300-openadk-linux-uclibc-objcopy

       /home/wbx/h8300/host_x86_64-linux-gnu/usr/bin/mkimage

Kernel 4.11.5 is tried to cross-compiled. The -a parameter to
mkimage is empty. What is the correct value?

I tried to use following patch, but the resulting kernel does not
boot on my device:
diff -Nur linux-4.9.20.orig/arch/h8300/Kconfig.cpu

Any ideas?
