Hi,

With "make ARCH=h8300 edosk2674_defconfig; make ARCH=h8300",
I see the following build error:

scripts/Makefile.build:44: arch/h8300/boot/dtb/Makefile: No such file or directory
make[1]: *** No rule to make target 'arch/h8300/boot/dtb/Makefile'.  Stop.

After fixing this up with

diff --git a/arch/h8300/Makefile b/arch/h8300/Makefile
index c2b24c9..f547870 100644
--- a/arch/h8300/Makefile

-core-y += arch/h8300/boot/dtb/

I get

This is with compiler and binutils built as you had provided earlier.

Other configurations fail to build with

h8300-unknown-linux-ld: cannot find arch/h8300/boot/dts/built-in.o: No such file or directory
Makefile:932: recipe for target 'vmlinux' failed
make: *** [vmlinux] Error 1

Switching from edosk2674_defconfig to h8300h-sim_defconfig without "make
mrproper" results in:

h8300-unknown-linux-ld: h8300s architecture of input file
`arch/h8300/boot/dts/built-in.o' is incompatible with h8300h output

---

Results are with git://git.sourceforge.jp/gitroot/uclinux-h8/linux.git,
branch h8300.
