Thanks for the feedback. From what we saw this works fine as long as
you also use these patches:

https://git.rtems.org/rtems/commit?id=dc9aaf7ced34501d7647a86b4c626c9cc056db01
https://git.rtems.org/rtems/commit?id=991fdb330be81c5cfb47f67fd032569809db6c41

These enable the FPU and initialize the core and FP registers, which
is needed by the TMS570's CCM.
