[U-Boot] Simple question about the TEXT_BASE
Hi everyone: I am a freshman in the embedded development area. I have a simple question about the TEXT_BASE. When I port the Das U-Boot to my S3C2440 board, I found that the TEXT_BASE equal to 0x33F8000 which is seen in the u-boot-xxx/board/smdk2410/config.mk. I want to know the function of this value and why this one be 0x33F8000. And, is this one changeable.Thanks for your kindly help! I am looking forward to your response!

TEXT_BASE is, in a general and coarse way, the address where the Uboot starts from the flash. For ARM architecture, instead, it's the relocation address, i.e. the ram address where the uboot relocates itself.
