U-Boot移植(10)u-boot重定位后的内存分布

对于smdk2410,RAM范围从0x30000000~0x34000000. u-boot占用高端内存区。从高地址到低地址内存分配如下：

　显示缓冲区                (.bss_end~34000000)

     u-boot(bss,data,text)  (33f00000~.bss_end)

     heap(for malloc)

     gd(global data)

     bd(board data)

     stack                        

     ....

     nor flash                      (0~2M)
