rtems source builder on flexible hardware (FPGA)

[Hoefle Marco]

Hello Chris,
thank you for the patch. I tried it and I got this:

I found a workaround to get the toolchain and the rtems kernel for our
Virtex-4 BSP using environment variables:

cd rtems-source-builder/rtems
export
'RTEMS_XPARAMETERS_H="/home/NANOTRONIC/hoefle/projects/customers/unibern
/ngms/toolchain_test/xparameters.h"'
export VIRTEX_CONSOLE_USE_INTERRUPTS=0
export VIRTEX_FAST_RAM_ORIGIN=0xfffe0000
export VIRTEX_FAST_RAM_LENGTH=0x0001ffec
export VIRTEX_RAM_ORIGIN=0x00000000
export VIRTEX_RAM_LENGTH=0x00200000
export VIRTEX_RESET_ORIGIN=0xffffffec

../source-builder/sb-set-builder --log=$TOOLCHAIN_DIR/4.11-powerpc.log
--prefix=$TOOLCHAIN_DIR --no-clean 4.11/rtems-powerpc-ngms.bset

This seems to work fine. I could build a simple RTEMS Test App and it
seems to run.
I am not sure if the current bsp approach is the best approach as parts
of the bsp information is given directly using the environment variables
and other parts are in the xparameters.h file.
The xparameters.h file contains all information but I would even prefer
not using it at all as it is Xilinx specific and the syntax could change
for example if different versions of the Xilinx tools are used.

Not the git sources. Does the attached patch help ? If it is ok I will 
push it.

Use as:

    --with-rtems-bspopts="options list"

Note, --without-rtems-tests is supported by the RSB.

Excellent. It is really nice to see this happening.
