Due to the way u-boot for 32-bit powerpc is compiled, the interrupt code assumes that the GOT pointer (r30) on u-boot is always intact. When making syscalls to u-boot, ensure that we have restored r30 like we found it before we enable interrupts to prevent u-boot from crashing if a timer interrupt was pending. This fixes ubldr on e500 qemu (assuming you have recompiled qemu's u-boot with API support!) Reviewed by: jhibbits Sponsored by: Tag1 Consulting, Inc.
