Sorry, not a GPU guy, can you point me to something that documents
this policy of 'only opensource compilers for GPU'?  I looked under
linux/Documentation and didn't see anything.

The current patchset doesn't have anything to do with FPGA toolchains
but you're using this patchset as a platform to talk about toolchain
issues.

It sounds like you are opposed to any kernel support of loading images
on FPGAs until all vendors have opensource toolchains.
