pxa270 strata flash驱动和hive注册表保存

我使用的平台是pxa270+sm501，bootloader和image存放在strataflash 中，设定为31M，那么剩余的1M空间可以作为存储用，注册表保存。bsp采用微软下载的mainstonIII，自带了strataflash 驱动。不过，好象需要CE5.01以上才能编译通过。所以拷贝CE5.0的public/common/oak/drivers/block/msflashfmd目录下的strata驱动，开始编译，顺便拷贝了fmd.h，编译时候需要这个头文件。设置注册表如下（参考了驱动开发网上的帖子）：

这样strataflash驱动被正常加载，CE启动后可以看到Flash文件夹，可以正常读写这个空间。

然后开始加载hive文件系统，添加了hive组建，在CE文档中关于hive有如下描述：

The run-time image originally did not include the hive-based registry, and a full clean build did not complete.

Be sure you complete a clean build after including the Hive-based Registry Catalog item in your OS design.

所以添加hive组建后一定要clean ,build and sysgen
