・HW情報や本体設定データを共通のTSFフォーマットにするため、TSF フォーマットのコードを追加。（現状はHW情報のみ対応） ・HW情報用のRSA鍵ペアを追加。 ・acsignライブラリにRSA暗号化関数を追加。 ・acsignライブラリのRSAでコード関数の値チェックを修正。 ・HW情報をライトするHWInfoWriterを追加。 ・NANDフラッシュマップ＆フォルダツリーのフォルダ構成における各ファイルに ついて、RSA署名の有無と使用する鍵による色分けを行う。 ・TWL_SystemMenuメモリマップにNANDファーム用バッファを記載。 （ランチャーとメモリが重ならないように） git-svn-id: file:///Users/lillianskinner/Downloads/platinum/twl/TwlIPL/trunk@312 b08762b0-b915-fc4b-9d8c-17b2551a87ff
