cross-compiling Linux for PowerPC e200 core?

[Németh Márton]

Hi,

I'm trying to cross-compile Linux 2.6.33 for Freescale MPC5554 [1][2]. This
microcontroller is based on the e200z6 core. I could build the cross-development
tools, but I could miss something because I get an error message when building
Linux for PowerPC e200 core. Here are the steps I used:

$ tar xjvRf binutils-2.20.tar.bz2
$ mkdir binutils-build
$ cd binutils-build
$ ../binutils-2.20/configure --target=powerpc-linux-gnuspe --prefix=/home/nmarci/usr/local
$ make
$ make install
$ cd ..
$ export PATH=$PATH:/home/nmarci/usr/local/binutils/bin
$ tar xjvRf gcc-core-4.4.2.tar.bz2
$ mkdir gcc-build
$ cd gcc-build
$ ../gcc-4.4.2/configure --target=powerpc-linux-gnuspe --prefix=/home/nmarci/usr/local --disable-shared --disable-threads --enable-languages=c
$ make all-gcc
$ make install-gcc
$ cd ..
$ tar xjvRf linux-2.6.33.tar.bz2
$ ln -s linux-2.6.33 linux
$ cd linux
$ make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnuspe- menuconfig
$ make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnuspe- vmlinux

I attach the kernel .config I used. I guess the assembler I built misses the support
for e200 core. How can enable it?
