[U-Boot] board doesnt boot when migrating from u-boot1.3.4 to u-boot2009.11.1

[sunr2007]

Dear all,
I was using u-boot-1.3.4 all these days . i decide to shift to new u-boot so
that i can use some new features . i compiled the latest u-boot-2009.11.1
.but my board doesnt boot at all . My board is based on  AT91SAM9261EK. i
did a couple of changes to u-boot which i'm listing below 
1) In the config file /include/configs/at91sam9261ek.h  i changed the line 
#define PHYS_SDRAM_SIZE			0x04000000	/* 64 megs */
to 
#define PHYS_SDRAM_SIZE			0x08000000	/* 128 megs */  since i have 128MB
SDRAM on my board.
 
and 
#define CONFIG_SYS_LOAD_ADDR                    0x22000000      /* load
address */
to 
#define CONFIG_SYS_LOAD_ADDR			0x27D00000	/* load address */
this is to reflect the change in bootstrap  code to copy u-boot to higher
address in SDRAM so tat RFS of size > 64MB can be copied .
 3) and finally in the file   
/home/ravikulkarni/denx/u-boot-2009.11.1/board/atmel/at91sam9261ek/config.mk 
i modified TEXT_BASE=0x23f00000 to TEXT_BASE=0x27D00000 to reflect the
change made for load address of u-boot in SDRAM 
 when i did the above changes it works for me in u-boot-1.3.4 but when i do
the same u-boot-2009.11.1 it doesnt  :( . so may i know is ther any other
new thing in new u-boot which im missing?  thanks.
warm regards,
Ravi kulkarni.
