[U-Boot-Users] [PATCH] powerpc: Backout relocation changes.

From: Grant Likely grant.likely@secretlab.ca
Ugh. I *hate* to back this change out, but these compiler flags don't work for relocation on all versions of GCC. I've not been able to reproduce the environment in my setup (and hence, not been able to find a combination that *does* work), so I've got no choice but to go back to the old gcc flags and linker script.
Signed-off-by: Grant Likely grant.likely@secretlab.ca --- Wolfgang,
I haven't had the opportunity to actually test this, and even if I did I've only got 1 compiler version installed and 2 architectures to test it on.
It is possible that it will cause breakage, but it is a straight revert of the original patches so it should be safe. (I recommend testing before the 1.3.0 release is cut)
Cheers, g.

Ugh. I *hate* to back this change out, but these compiler flags don't work for relocation on all versions of GCC. I've not been able to reproduce the environment in my setup (and hence, not been able to find a combination that *does* work), so I've got no choice but to go back to the old gcc flags and linker script.
Hi Grant,
This linker script needs a similar change too: board/ads5121/u-boot.lds
kind regards, Rafal

Hmmm, looks that linker script should also be moved to cpu/mpc5121 like has been done for all other powerpc boards.
Good catch, thanks! g.

It works with both compiler versions here, thanks. Tested-By: Rune Torgersen runet@innovsys.com

Wolfgang,
I haven't had the opportunity to actually test this, and even if I did I've only got 1 compiler version installed and 2 architectures to test it on.
It is possible that it will cause breakage, but it is a straight revert of the original patches so it should be safe. (I recommend testing before the 1.3.0 release is cut)
Applied, thanks.
Best regards,
Wolfgang Denk
