[U-Boot,v9,07/15] ARM: Fix arm720t SPL build

Take a few SPL fixes from armv7 and apply them to arm720t:
-Use dummy exception handlers for SPL build
-Initialize relocation register r9 to 0 for the case of no relocation
-ifdef out interrupt handler code

Hi Allen,

I have already do a patch to fix all the arm common issue:

http://patchwork.ozlabs.org/patch/174471/
[V2] arm: Fixed the offset for the no relocation.

Thanks,

Thanks for pointing that out, what's the status of that patch?  Is it
being reviewed for u-boot/master?  My patch is being carried in the
u-boot-tegra/master tree and Tom is about to issue a pull request for
u-boot-arm.  If your patch is going up first I can rebase mine on top
of that.

At first, I fix the issue in arm1176 and send it in my s3c64xx patch
thread, But Albert suggest me to correct all the arm platform.

Up to now, I have not o receive any response from the patch.

1. Somebody is using my non-u-boot e-mail address for u-boot mails... 
Anyone, please make sure you're using albert.u.boot@aribaud.net, not 
albert.aribaud@free.fr.

2. I'll check Hongbo's patch series sometime on Sunday and do some 
regression on it.

Amicalement,
