[ECOS] [EB40]why redboot check my RAM smaller?

[zhuyong]

hi list,
I download ecos packages from ecos snapshot five days earlier.
I have one customed board based on AT91M40800(AT91X40),is similar with EB40.
I have 1M FLASH and 2M SRAM on board,and address as follows:
flash: 0x01000000-0x010FFFFF
sram:  0x02000000-0x021FFFFF
so I change packages/hal/arm/at91/eb40/current/include/hal_platform_setup.h:
_InitMemory:            
        .long   0x0100202E  // 0x01000000, 1MB, 8-bit, 
        .long   0x02002081  // 0x02000000, 2MB, 16-bit
I build redboot_rom.bin and download it to 0x0101000,but redboot start and
have this info through serial as follows:
RedBoot(tm) bootstrap and debug environment [ROM]
Non-certified release, version UNKNOWN - built 16:39:53, May 24 2004

Platform: Atmel AT91/EB40 (ARM7TDMI) 
Copyright (C) 2000, 2001, 2002, Red Hat, Inc.

RAM: 0x02000000-0x02080000, [0x02005328-0x02080000] available
RedBoot> 
why available RAM is so small, can i load one file larger than 800k to RAM?

regards
zhuyong
