2. カーネルビルド
メインラインのカーネルが、sheevaplugに対応しているそうなので、www.kernel.orgからソース取得。
公開キー取得した後、署名チェック。 (一応)
$ gpg --keyserver wwwkeys.pgp.net --recv-keys 0x517D0F0E
$ gpg --verify linux-2.6.35.tar.bz2.sign
$ gpg --verify linux-2.6.35.tar.bz2.sign
http://sheeva.with-linux.com/sheeva/からパッチ+configファイルを落としてくる。2.6.35用のは無いので、2.6.34.2用のを。
落としてきたパッチの内、
- 0001-Kirkwood-Marvell-GuruPlug-support-2.6.34.patch
- 0002-Driver-for-Marvell-Libertas-8688-SDIO-micro-AP-suppo.patch
- 0003-Initial-defconfig.patch
は、GuruPlug用？っぽいので、ほっとく。
- linux-2.6.29-usb-serial-evdo.patch
を当てると、２カ所NG。だったので、手パッチ。

- mvsdio-1-2.6.30.patch
- mvsdio-2.patch
この２つのパッチ(udelay入れるパッチ)は普通に適用できた。
configファイルをリネーム。
$ cp sheeva-2.6.34.2.config linux-2.6.35/.config
$ cd linux-2.6.35
$ vi .config
$ cd linux-2.6.35
$ vi .config
CONFIG_SATA_MV=m
をm から yへ変更しておく。
あとで、libncurses-dev, uboot-mkimage, tftpdが必要になるので、インストールしておく。
$ LANG=C sudo aptitude install libncurses-dev uboot-mkimage tftpd-hpa
$ ln -s /var/lib/tftpboot ~/tftpboot
$ sudo chmod a+w ~/tftpboot
$ ln -s /var/lib/tftpboot ~/tftpboot
$ sudo chmod a+w ~/tftpboot
準備が整ったのでので、カーネルビルドを。順番は↓こんな感じで。
- make menuconfig
- make
- make uImage
- make modules
- make modules_install

何もせず「Save an Alternate Configuration File」で保存。そのあと、
