uboot解决DRAM无法正确识别的问题

终于解决了DRAM无法正确识别的问题，吼吼～

参考修改代码：

./include/configs/ok6410.h:#define PHYS_SDRAM_1_SIZE  0x10000000 /* 256 MB */

#define DMC1_MEM_CFG 0x0001001A

 board/feilin/ok6410/lowlevel_init.S  
 mmu_table:将  
        // 128MB for SDRAM 0xC0000000 -> 0x50000000  
        .set __base, 0x500  
        .rept 0xC80 - 0xC00          
        FL_SECTION_ENTRY __base,3,0,1,1  
        .set __base,__base+1  
        .endr  
  
        // access is not allowed.  
        .rept 0x1000 - 0xc80          
        .word 0x00000000  
        .endr  
  
修改为：  
        // 256MB for SDRAM 0xC0000000 -> 0x50000000  
        .set __base, 0x500  
        .rept 0xd00 - 0xC00  
        FL_SECTION_ENTRY __base,3,0,1,1  
        .set __base,__base+1  
        .endr  
  
        // access is not allowed.  
        .rept 0x1000 - 0xd00  
        .word 0x00000000  
        .endr

不用修改uboot自举地址仍然默认为ox57e00000
