[U-Boot] [PATCH] qemu-ppce500: Align code at 64k boundary
The QEMU u-boot located itself at a 4k aligned offset which the rest of the code didn't really expect. Align it with 64k to allow the memory code to deal with 64k granularity.
This fixes broken interrupt delivery with the ppce500 machine for me.

I think we have a similar problem with NAND, SD, etc. boot on some targets. I'll try to fix it so that the existing addresses work.

Scott,
I lost track on your progress. Please let me know if I should hold this one or drop it.

It shouldn't be needed anymore, as of commit e1bfd1c6b7bc0dc530247fd9108feba3147adf36 ("powerpc/mpc85xx: Use GOT when loading IVORs post-relocation").
