BSP variants

[Joel Sherrill]

BSP variants are recognised by *.cfg in make/custom.

configure. ac uses some macros to define conditional variables differently based on the variant. Look BSP SETOPTS or similar in the arm lpc BSPs or PowerPC gen5200 for examples.

I'm not understanding how to build multiple BSP variants from a single libbsp/<cpu>/<bsp> directory.  The ARM lpc32xx does this, for example.  Configuring to for a BSP named lpc32xx_mzx ends with the message:

target architecture: arm.
available BSPs: lpc32xx_mzx.

even though there is no libbsp/*/lpc32xx_mzx directory and it isn't mentioned in libbsp/<cpu>/acinclude.m4.  Doing 'make all' then goes and builds everything, as expected.  Where is the lpc32xx_mzx target defined?  Is it in the make/custom directory?

When I follow this same pattern with the names zc702 and zedboard for the zynq BSP directory, the configure works, but the 'make all' fails with 'Invalid BSP'.

        Thanks,
