enable-smp on xilinx_zynq_zedboard

[Ric Claus]

Hello All,

  Today I git cloned the RTEMS master and configured with:

../../src/rtems/configure --target=arm-rtems4.11 --enable-posix \
--enable-networking --enable-cxx --enable-maintainer-mode --enable-tests \
--enable-rtemsbsp=xilinx_zynq_zedboard --enable-smp \
--prefix=/home/claus/development/rtems/4.11 BSP_PRINT_EXCEPTION_CONTEXT=1

and built.  The build failed with:

I remember Sebastian’s patch email titled "[PATCH] rtems: Add rtems_interrupt_local_disable|enable()” of a month ago.  Since the L1 cache functions of the Zynq are visible only to the local core, is it appropriate to replace the rtems_interrupt_disable|enable functions with rtems_interrupt_local_disable|enable in this file?  Or do we need a more involved solution, in which case, could I please get some guidance?

  Thanks very much!

  Cheers,
