U-Boot系列之一： S3C2410内存映射结构
U-Boot系列之一： S3C2410内存映射结构
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。。。
现在明白了没，其实就那么多东西，我们控制外设接口的时候，无非就是往寄存器里面写东西，而写东西的程序就是驱动程序，应用程序只要调用驱动程序就可以了，至于各个外设怎么和处理器联系起来的，那是硬件的东西，我们现在可以不用管（当然了，能知道原理更好，可以直接看原理图，做PCB板子了）。
下篇文章我们将看看各个部分（启动代码，文件系统以及内核）在flash中的布局，以及搬运到内核后的布局。
