这片文章主要介绍S3C2410的内存映射,主要参考2410的用户手册。

   我用的板子是基于三星的2410,三星的内存片选有8个bank,这里所谓的bank我开始也不是很清楚,在网上搜了一通也不知所云,但是当我看了 2410的用户手册后才有点明白,这里的bank就是片选,一个片选就是一个bank,在U-Boot中,配制的时候要配制SDRAM和FLASH的 bank数,那么如果你的SDRAM或者FLASH就接了一个片选的时候,就定义为1就可以了,其他的类推。

  下面是2410的内存映射图,2410和其他的大部分的处理器一样,支持NorFlash和NANDFlash启动,而这两种启动方式内存所映射的地址不怎么相同,我的板子没有NANDFlash,所以就以从NorFlash启动为例子了:

==============================================<-------0xFFFF_FFFF
|     NOT USED
==============================================<-------0x6000_0000
|     SFR Area  (各个接口的控制寄存器)
==============================================<-------0x4800_0000
==============================================<-------0x4000_0FFF
|     BootSRAM         (4KBytes)
==============================================<-------0x4000_0000
|     SROM/SDRAM     nGCS7    (bank7)
==============================================<-------0x3800_0000
|     SROM/SDRAM     nGCS6    (bank6)
==============================================<-------0x3000_0000
|     SROM   nGCS5    (bank5)
==============================================<-------0x2800_0000
|     SROM   nGCS4    (bank4)
==============================================<-------0x2000_0000
|     SROM   nGCS3    (bank3)
==============================================<-------0x1800_0000
|     SROM   nGCS2    (bank2)
==============================================<-------0x1000_0000
|     SROM   nGCS1    (bank1)
==============================================<-------0x0800_0000
|     SROM   nGCS0    (bank0)
==============================================<-------0x0000_0000

    上面的每个bank最大支持128M,除了bank0,其它的每个bank都支持8/16/32位操作,bank0只支持16/32位操作,在我的板子上,Flash接bank0,一共8M,16位,SDRAM接bank6,一个32M,32位。所以启动的时候,CPU从0x0000_0000开始执行,而在这上面的NorFlash,存放的是U-Boot,用于启动Linux的。
    而我们目前所做的工作就是要把U-Boot移植成功,然后烧写到该地址,假设你的板子的供应商已经提供了少些的工具,等到我们少些成功,我们就可以通过网络来加载Linux,通过串口来调试了,至于怎么做的,我们慢慢来,以后的帖子会涉及到。。。
    在上面的存储地址布局中,SFR Area就是各个接口控制器的地址,我们可以把它定义如下,来自华恒PPCboot上面的源代码中的头文件s3c2410.h:

    一下子搬出这个多是不是有点头晕?呵呵,其实我们不必一个一个的看,看也没用,我们需要的时候会接触到的,比如串口的配制,就那么几个寄存器,会搞熟的,要根据具体的应用来学,要不很累的,哈哈,一点愚见。。。
