Dear Simon Schwarz,

please don't use TOFU, use inline quoting and also send to the list.

Sounds correct.

Yes, armv7 start.S initializes .bss to zero in normal case (after relocation -> see clear_bss). Is that called in your case (SPL with not mainline code) too?

Yes, if it is initialized correctly (zero out the bss section!), remember our talk some days ago.

But I just guessing cause of your statement 'the function pointer are initialized to garbage' in your first mail, it may be a completely other cause. Please let us know what it was.
