[kbuild-devel] Kbuild 2.5-2.3 for SuperH

[Greg Banks]

G'day,

Here's the SuperH patches for kbuild-2.5 upgraded to 2.3 (kernel 2.5.12).

There's no functional change except that 2.5.12 is even less broken
so the "hacks" patch is gone.

I'll update to 2.4 (2.5.13) sometime after 2.5.13 is merged into LinuxSH.

Greg.

KBuild-2.5 for the SuperH Linux port
====================================

Here's how to build a LinuxSH kernel using kbuild-2.5.

Ingredients
-----------

linux-2.5.12.tar.bz2                Linus tarball from ftp.kernel.org

linuxsh-2.5.12.tar.bz2              LinuxSH tarball from linuxsh.sf.net

kbuild-2.5-core-9.bz2               KBuild 2.5 core patch from kbuild.sf.net

kbuild-2.5-common-2.5.12-1.bz2      KBuild 2.5 common patch from kbuild.sf.net

kbuild-2.5-sh-2.5.12-1gnb.bz2       KBuild SuperH patch, from here

kbuild-2.5-shcommon-2.5.12-1gnb.bz2 KBuild common intersection with SuperH
                                    patch, from here


Procedure
---------

1.  Extract linux-2.5.12.tar.bz2 into a directory linux-2.5.12

2.  Apply patches to linux-2.5.12 (the order matters)

    * kbuild-2.5-core-9.bz2
    * kbuild-2.5-common-2.5.12-1.bz2
    * kbuild-2.5-sh-2.5.12-1gnb.bz2
    * kbuild-2.5-shcommon-2.5.12-1gnb.bz2
    
3.  Checkout (or extract) linuxsh-2.5.12

4.  Make the directory where all the build output will go

    mkdir obj
    
5.  Setup environment variables (in bash syntax).  Note that the
    full pathnames and trailing /s are significant.

    export KBUILD_SRCTREE_000=$PWD/linux-2.5.12/
    export KBUILD_SRCTREE_001=$PWD/linuxsh-2.5.12/
    export KBUILD_OBJTREE=$PWD/obj/

6.  Copy your .config into $KBUILD_OBJTREE and

    make \
        -f $KBUILD_SRCTREE_000/Makefile-2.5 \
        ARCH=sh CROSS_COMPILE=sh-unknown-linux-gnu- \
        oldconfig

7.  Do the actual build

    make \
        -f $KBUILD_SRCTREE_000/Makefile-2.5 \
        ARCH=sh CROSS_COMPILE=sh-unknown-linux-gnu- \
        installable

8.  Install the results

    make \
        -f $KBUILD_SRCTREE_000/Makefile-2.5 \
        ARCH=sh CROSS_COMPILE=sh-unknown-linux-gnu- \
        install
