[U-Boot] [PATCH] qemu-ppce500: Align code at 64k boundary

[U-Boot] [PATCH] qemu-ppce500: Align code at 64k boundary

[Alexander Graf]

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").
