一款交换机BSP开发代码

init.s:
ctrl 地址改变：
从CTRL_CODE_ADDR EQU $100E0000	改成
  CTRL_CODE_ADDR EQU $101E0000

ctrl执行地址改变：
从 CTRL_CODE_ADDR1  EQU  $00340000; CTRL Address in DRAM
   CTRL_CODE_ADDR2  EQU  $00340434; CTRL CODE begin Address in DRAM
改成
   CTRL_CODE_ADDR1  EQU  $002e0000; CTRL Address in DRAM
   CTRL_CODE_ADDR2  EQU	 $002e0434; CTRL CODE begin Address in DRAM

CRC存放地址改变：
从CTRL_CODE_CRC EQU $100FFFF0	; CTRL Code CRC address
改成
  CTRL_CODE_CRC EQU $101FFFF0	; CTRL Code CRC address

FLASH大小改变：
从FLASH_LENGTH EQU $100000
改成
  FLASH_LENGTH EQU $200000

AL300地址cs3的设置修改，调试的时候定

main.c修改
 #define	CTRL_CODE_ADDR		0xe0000		// CTRL in Flash (offset)
改成：#define	CTRL_CODE_ADDR		0x1e0000	// CTRL in Flash (offset)

flash.h修改
 #define FLASH_MEMORY_SIZE  	0x00100000		// 1M bytes(512K words)
改成：#define FLASH_MEMORY_SIZE  	0x00200000		// 1M bytes(512K words)
