Dear "GROYER, Anthony",

The former is the entry point address, while the latter is the start
of the text segment.  These may be the same (and on many ARM systems
they are),  but they have actually no direct relation to each other
(and some ARM systems do use an entry point that is not the same as
the start of the code).

Please better not confuse these two...

Best regards,

Wolfgang Denk
