Why not shows 64M flash inform

seapeak

Hi
After my u-boot which was modified from u-boot1.1.2(Lubbock board file)was downloaded into flash,I rebooted my board .The minicom showed as followed:
U-Boot code: A3F80000 -> A3F9E9F0  BSS: -> A3FD3480
RAM Configuration:
Bank #0: a0000000 64 MB
Bank #1: a4000000  0 kB
Bank #2: a8000000  0 kB
Bank #3: ac000000  0 kB
Then it stopped here.
Why not shows 64M flash information and etc?
My board is similar as lubbock board.
regards
