[U-Boot] Difference between CONFIG_SYS_TEXT_BASE and _start

[Djoker]

Hi Everyone,

I have a armv7 board and am seeing a discrepancy.

In my board file I have defined:
#define CONFIG_SYS_TEXT_BASE 0x67000004

After I build the ub-boot binary, I ran "nm u-boot | grep -w _start".
It returned the following:
67000020 T _start

Would anyone know why there is a difference in the values of _start
and CONFIG_SYS_TEXT_BASE ? I thought they were the same, please
correct me if wrong ?

Thanks,
~vj
