Do you think that this is the best way how to handle this?
We are targeting small uboot running from OCM on Zynq. Moving ifdef to
function itself will caused that we will waste some bytes which do nothing.
Reference in table stays there and then return from that function too.
It it is not huge but this way seems to me better.
But no problem to change it if you think that this is the best way how
to handle this.
Thanks,
Michal
