移植HG255D的编译参数到openwrt的trunk中

hoow***

参考了帖子：https://www.right.com.cn/forum/forum.php?mod=viewthread&tid=80205

后发现到现在trunk里也没有HG255D的支持，于是自己做移植。

一共修改了这些文件：
?       target/linux/ramips/files/arch/mips/ralink/rt305x/mach-hg255d.c
M       target/linux/ramips/files/arch/mips/ralink/rt305x/Kconfig
M       target/linux/ramips/files/arch/mips/ralink/rt305x/Makefile
M       target/linux/ramips/files/arch/mips/include/asm/mach-ralink/machine.h
M       target/linux/ramips/image/Makefile
?       target/linux/ramips/rt305x/profiles/hg255d.mk
M       target/linux/ramips/rt305x/config-3.3


其中marc-hg255d.c文件要做修改，因为dreambox使用的backfire版跟trunk版有一些函数接口不一样了。所以我吧led灯和button的配置一并注释掉。

然后我进行标准的编译，多余的软件一概不加。 编译万事后成功了。通过USB-TTL刷机。可以刷进去。

能看到kernel启动了。但是发现找不到根文件系统。

我跟一些朋友商量他们说是由于mtd的配置信息不正确。但是我实在是不知道怎么改mtd的配置信息，不是很了解， 不知道有没有人能帮我下？

我可以提供移植用的那几个配置文件。
现在配置文件信息已经提供了，请下载附件：

还有一个问题，我发现我make过程中如果有问题，我去修改mach-hg255d.c修改完继续make发现不会识别修改。只能make clean再make V=99这样是不是很二啊，有木有智能点的方法？

非常感谢，哈哈。
这样就有新内核用了。

这个可顶一下,希望你能快一点出个固件,我们可以刷机了.

fireback版和trunk还有dreambox这几个词都是什么关系啊？英文官网里最新版还有Attitude Adjustment一词，让人非常迷惑啊！

usa***

高手啊，期待更完善

where is the doc about HG255D hardware? How did you know the pin defination?
