求助：前不我刚买了块友善的Micro2440板子，准备把ecos移到上面，但redboot移植没有成功。想请高手指点一下Micro2440内存布局文件应该如何进行配置？如果有移植成功的redboot就更好了。
我选的是RAM启动的方式。
板子的资源如下：
CPU CORE ：ARM920T
内存：SDRAM 64M 物理地址：BANK6 0x30000000---0x34000000
bootrom : NORFlash ：2M
片上SRAM：4K 物理地址：可根据启动方式不同映射为0x40000000（NOR启动）、0x0（NANA启动）
下面是我现在有内存布局文件：
/ eCos memory layout - Fri Oct 20 05:43:59 2000
// This is a generated file - do not edit
#ifndef __ASSEMBLER__
#include <cyg/infra/cyg_type.h>
#include <stddef.h>
#endif
#define CYGMEM_REGION_ram (0x0)
#define CYGMEM_REGION_ram_SIZE (0x4000000)
#define CYGMEM_REGION_ram_ATTR (CYGMEM_REGION_ATTR_R | CYGMEM_REGION_ATTR_W)
#define CYGMEM_REGION_sram (0x30000000)
#define CYGMEM_REGION_sram_SIZE (0x1000)
#define CYGMEM_REGION_sram_ATTR (CYGMEM_REGION_ATTR_R | CYGMEM_REGION_ATTR_W)
#ifndef __ASSEMBLER__
extern char CYG_LABEL_NAME (__heap1) [];
#endif
#define CYGMEM_SECTION_heap1 (CYG_LABEL_NAME (__heap1))
#define CYGMEM_SECTION_heap1_SIZE (0x4000000 - (size_t) CYG_LABEL_NAME (__heap1))
