      Dear Reinhard Meyer,

I agree here. _If_ relocation, it should work without hand-adding
fixup stuff to all functions using initialized data with pointers.
Even Wolfgang forgot to fixup his 2nd level command table in
cmd_nvedit.c ;)
I didn't forget it - at least not in the sensse that I think this is
something that needs to be done.
This works fine on PPC with relocation, and we should make it work
the same on other arches.
...
And, for space concerns in flash, relocation should always be an
option on a board by board basis...
NAK.
...
And as an idea, if position independent code is used, only pointers
in initialized data need adjustment. Cannot the linker emit a table
of addresses that need fixing?
It does. That's the GOT.
Best regards,
Wolfgang Denk

I thought my people would grow tired of killing. But you were  right,
they  see it is easier than trading. And it has its pleasures. I feel
it myself. Like the hunt, but with richer rewards.
