[U-Boot-Users] Global Data Pointer

[Peter Pearse]

Hi

I don't understand the way the global data pointer (gd) is implemented
in u-boot.

Why is declared as a local register variable (in functions that access
it), rather than a global register variable?

I know this more a gcc question, rather than u-boot, but perhaps someone
in the group has time to enlighten me, or point me to some
documentation.

Regards

Peter
