[U-Boot-Users] how to Relocate arm startup code

Hi,
I am working on a customized arm926ejs versatile board. My board has SDRAM at reset vector i.e., @ 0x00 and FLASH is located at a different higher lcoation. At Boot up, SDRAm is mapped to Flash. I have to enable few register and enable sdram chip. @ reset the arm uboot startup code has
b reset
which point to TEXT_BASE + 0x50 which in my case falls to uninitialized SDRAM and hence it fails. So i have to hard code the startup to point to my flash location. so
Instead of b reset
i have ldr pc, _flash_reset
where _flash_reset: .word (CFG_FLASH_BASE + reset - TEXT_BASE)
So i want to know if there is any better alternative to this instead of hard coding. Also i would like to know how this taken care of for versatile board.
