Kernel 2.6.17.4 on SH7780

2.6.17.4のカーネルが、SH7780で動きました。
ディスクは、/dev/hdaとmtdを併用しています。

2.6.10の時よりも安定している模様。
意味不明のハングアップはなくなった。

次の表は、SH-Linuxからの変更点のまとめ。

変更モジュール	変更内容
arch/sh/drivers/pci/ops-se7780.c	PCIバス初期化、INTA,INTB,INTC,INTDの定義(新設)
include/asm-sh/se7780/map.h	ボード上のレジスタのアドレス(新設)
include/asm-sh/se7780/io.h	ボードのI/O操作用の関数のプロトタイプ(新設)
include/asm-sh/se7780/irq.h	ボードの割り込み定義(新設)
include/asm-sh/se7780/irq.h	ボードの変数の定義(新設)
arch/sh/boards/hanada/se7780/setup.c	machine_vectorとFPGAの初期化(新設)
arch/sh/boards/hanada/se7780/io.c	新設
arch/sh/boards/hanada/se7780/led.c	HeartBeat用のコード(新設)

以下、起動時の出力。
