ppc/85xx: Fix crashes due to generation of SPE instruction
U-Boot crashed on the last instruction:
int parse_stream_outer(struct in_str *inp, int flag)
{
effa4784: 94 21 ff 38 stwu r1,-200(r1)
effa4788: 7c 08 02 a6 mflr r0
effa478c: 42 9f 00 05 bcl- 20,4*cr7+so,effa4790 <parse_stream_outer+0xc>
effa4790: 7d 80 00 26 mfcr r12
effa4794: 13 c1 b3 21 evstdd r30,176(r1)
...which is a SPE instruction, although -mno-spe was used.
tmp/cross/ppce500v2/bin/powerpc-angstrom-linux-gnuspe-gcc --version
powerpc-angstrom-linux-gnuspe-gcc (GCC) 4.3.3
Seems to be a known issue (since 2008-04?!)
Googled some, turns out this patch/workaround works for me on MPC8536DS.
See http://gcc.gnu.org/ml/gcc-patches/2008-04/msg00311.html for more info
