Re: [U-Boot-Users] [PATCH][FOR 1.3.4] 85xx: Don't move interrupt vector to low memory

Good point. Why don't we factor this out and make it common code for all PPC?

Because the relocation is specific to the various interrupt types. Book-E will need different code for handing IVPR/IVORs than classic.

Umm... the exception code itself may be different, but does this imply that the code used to copy / relocate the exception handlers to low mem must be different, too?

Maybe. But then, these can use exception vectors at low mem, too, right?

They can, but it has to be setup.

What is Linux doing?
