Problems running RTEMS on Raspberry Pi2

[Nils Hölscher]

Hi,

I think r7 no longer holds the expected value in line 242
<https://git.rtems.org/rtems/tree/bsps/arm/shared/start/start.S?id=bdec62c4d5aa25e5a98b9fafe78936a7beb96a6e#n242>
and
that is why it breaks.
In the old file r7 was holding the value after this
<https://git.rtems.org/rtems/tree/bsps/arm/shared/start/start.S?id=af80b0a3406bef73dc6550421947a981c939da27#n155>
instruction.
however this not he case in the newer version.
r7 is used as destination register in more instructions and not only for
holding the stack sizes.

Best,
Nils
