[U-Boot-Users] -mrelocatable

[Woodruff, Richard]

Perhaps I read the fragment wrong.  We needed to apply this patch as the
relocate option generated bad code or code which would not compile using
a version of GCC3.4 (depending on the relocation address it would fail
to compile or compile and generate bad code).

In general I think there are also changes which were made to the u-boot
source structure to allow them to compile properly with newer GCC's.
The provide patch is necessary for ARM boards with some recent versions
of GCC.  If your compiler already works, then disregard the message.

Regards,

Richard W.
