a question about relocate_code in start.S

im reading the code of u-boot

in <u-boot>/cpu/mpcxx/start.S
under >relocate_code< symbol

i can't figure the difference between _branch 1_ & _branch 2_ why cmp _the start addr of the future code in the mem_ and _the start of the flash_ ??

thnx
best regards

Please try to be a bit less cryptic. Which exact parts (lines) of the code are you referring to?

I can neither find any references to "branch 1" or "branch 2" or "future code" or anything like that in the whole source tree.

Best regards,
