[U-Boot-Users] a question about relocate_code in start.S

[YanMin Qiao]

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,

Wolfgang Denk

We are all agreed that your  theory  is  crazy.  The  question  which
divides  us  is  whether it is crazy enough to have a chance of being
correct. My own feeling is that it is not crazy enough.  - Niels Bohr
