[U-Boot-Users] u-boot TEXT_BASE relocatable

Hey fellas, I am in a fix...and am a newbie... I have my u-boot for ARM926Ejs... And there are two DDR banks. The problem is I want to be able to run u-boot from both the banks...

Reason? I need to do DDR testing (so need to change the offset values at times in the control registers of the DDR)... So if u-boot runs from Bank A, I can test Bank B, but as soon as I try and change control register of Bank A...my system crashes or resets... So I want to somehow use offsets to be used by the linker... Is that possible? And can nething be done to TEXT_BASE value in CONFIG.MK file to do this ?

thanks alot in advance guys

Sincerely Jayant
