Applied to u-boot/master, thanks! Note that I don't yet see a work-around for the gcc 4.7 issue, and I really want to see that for -rc3.

I can confirm above. Also the tam3517 som (omap3) fails to boot due to mentioned commit. The patch from Tetsuyuki is arch specific (rmobile) so that won't fix the omap case. Reverting the patch, 63ee53a, does help.
Is there anything against reverting the patch (at least for the release...)?

Here is my opinion:
1) I think patch 63ee53a7 is right in considering there is no need for cpu_init_crit to save lr in ip before calling lowlevel_init especially considering this is a tail call.
Only lowlevel_init can tell if it uses ip or lr for its own purposes, thus any saving of ip and/or lr due to the workings of lowlevel_init should be performed in lowlevel_init.
2) I am not sure that the patch in this discussion depends on 63ee53a7, because IIUC, the patch simply saves ip "on a stack" then lr into ip, and after running s_init, restores from ip and ip from the stack; it never assumes ip contains a return address.
I know we're that close to the release, but I want to be sure we understand what needs fixing. Kobayashi, Jeroen, can you indicate precisely how the issues you encounter are related to 63ee53a7?

Here is my opinion:
- I think patch 63ee53a7 is right in considering there is no need for
cpu_init_crit to save lr in ip before calling lowlevel_init especially considering this is a tail call.
Only lowlevel_init can tell if it uses ip or lr for its own purposes, thus any saving of ip and/or lr due to the workings of lowlevel_init should be performed in lowlevel_init.
- I am not sure that the patch in this discussion depends on 63ee53a7,
because IIUC, the patch simply saves ip "on a stack" then lr into ip, and after running s_init, restores from ip and ip from the stack; it never assumes ip contains a return address.
I know we're that close to the release, but I want to be sure we understand what needs fixing. Kobayashi, Jeroen, can you indicate precisely how the issues you encounter are related to 63ee53a7?

Note that the patch that Tetsuyuki says also breaks SPL support for OMAP3 boards, at least my IGEP boards doesn't boot and hangs at SPL level.

I can confirm above. Also the tam3517 som (omap3) fails to boot due to mentioned commit. The patch from Tetsuyuki is arch specific (rmobile) so that won't fix the omap case. Reverting the patch, 63ee53a, does help.
Is there anything against reverting the patch (at least for the release...)?

Hmm... I notice only now that I had mentally 'fixed' the order of the restoring lines removed by the patch. Had they been in the right order (mov lr, ip then ldr ip, [sp]) the original code would have worked, albeit probably useless.
I suspect that the bad ordering was actually a mistake unseen, and that the dependence on ip being a return address is only due to this mistake.
In any case, this makes me *more* determined that 63ee53a7 is right,as well as this patch.
Jeroen, I suspect that your problem comes from the fact that the same bug that this patch uncovers and fixes exists also in
arch/arm/cpu/armv7/omap3/lowlevel_init.S (lines 216-218 and 228-229)
... and would be better fixed there than by reverting 63ee53a7.

I have the same opinion as Albert. 63ee53a7 is right. It should not be reverted. lowlevel_init.S in rmobile and omap have mistake, it should be fixed.
I checked 2012.10-rc3. It has already done. Thank you very much.
Hi Albert, sorry for late response.

Hello, Albert Hello, Tom Thank you for merging my patches.
I checked current u-boot-master and found kzm9g board fails to boot because bug. This bugfix patch solves it. I think 2012.10 release should have this bugfix.
Iwamatsu-san, could you double check this patch?

Is this load of sp still needed?
Yes. At this point sp is not yet initialized and s_init() uses stack area.
- str ip, [sp] /* stash old link register */
- mov ip, lr /* save link reg across call */
- bl s_init
