Dear all,
I used a platform "migo-R" which cpu is SH7722.
I download a android kernel source "linux-2.6.25-
android-1.0_r1.tar.gz" from "http://code.google.com/p/android/
downloads/list".
The toolchain is "gnush4-nofpu_linux_v0701-1.tar.gz".
http://www.superh-linux.org/platforms/index.html#sh7722migor
(step 1). I set up "NFS" from migo-R to the Host PC.
(step 2). Generate the default .config for the kernel using the
migor_default config ,the config file found /kernel/arch/sh/configs/
migot_defconfig (ARCH is case sensitive) --> make migor_defconfig
ARCH=sh
(step 3).When I complier the kenel,it will be something wrong. The
binder source code seems to be lacked some file,so I modify the binder
to module<M> in the kernel. Then it continues to complier to generate
uImage.
(step 4). I use the U-boot to start the uImage.

I check to file system.
[r...@mirl194052 rootfs]# file init
init: ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically

The questions are (1)Do I have do something error ?,(2) Is the init
for ARM cpu, not for SuperH cpu (3) How to generate the init file for
superH? (4) Is Android supported the SuperH(sh7722)?
