上次用将29内核的6410驱动移植到android的27内核，结果发现很多驱动程序29内核都没有做，仅仅移植了一个网卡驱动就异常痛苦
感觉开发板提供的2.6.24内核驱动比较丰富，还是将24内核移植到android的27内核吧
虽然内核变化比较大，过程蛮痛苦。

一大堆的头文件不匹配，各位看着办，可以用新形式，也可以用old，反正咱们只用6410一款处理器

arch/arm/mach-s3c6410/s3c6410.c:137: error: implicit declaration of function 'set_kset_name'
arch/arm/mach-s3c6410/s3c6410.c:137: error: initializer element is not constant

#define set_kset_name(str) .kset = { .kobj = { .name = str } }
本来是添加以上内容的，后来发现不应该这样做
有几个地方
比如
struct sysdev_class dma_sysclass = {
//set_kset_name("s3c64xx-dma"),
.name = "s3c64xx-dma",
.suspend = s3c_dma_suspend,
.resume = s3c_dma_resume,
};
set_kset_name已经非弃用，直接用 .name = "s3c64xx-dma",即可
还有这儿也是
struct sysdev_class s3c6410_sysclass = {
.name = "s3c6410-core",
};

手动定义zreladdr = 0xc0008000?
