[Skiboot] [PATCH 00/17] FSP code free OPAL

[Stewart Smith]

This is mostly an RFC series, although I'd be interested in thoughts on
merging it. This does the bulk of the work to allow us to build a
skiboot without all the FSP support, which has had various tentacles
into core code for hysterical raisins.

It gets us a modest (52kb xz compressed, ~200k uncompressed) image size
benefit.

I've also done it in a way that would allow us to just have two link
targets, a skiboot-fsp.lid and a skiboot.lid (or a skiboot-nofsp.lid)
rather than it be an actual build option, which is something I kind of
like to be able to do.

I've only boot tested in qemu so far, so YMMV here :)

Stewart Smith (17):
  op_display: make platform function rather than "FSP" specific
  Move more FSP functions to FSP platform
  Split FSP OCC code out into hw/fsp/
  Move core/hostservices.c to platforms/ibm-fsp/
  host_services_occ_base_setup is core homer code not host_services
  core/init.c: use if (platform.bmc) rather than !fsp_present()
  core/init.c: no longer need to include FSP headers
  Move FSP specific op-panel calls to platform.exit()
  core/opal: move HIR trigger to FSP poller
  hw/fsp/fsp.c: remove lying comments
  core/pci: use !platform.bmc hack over fsp_present()
  fast-reboot: move platform specific bits to a platform call
  Move FSP-specific VPD functionality to platforms/ibm-fsp/
  core/timer: Use platform heartmeat_time call for FSP platforms
  Separate FSP specific PSI code
  Move platform specific PRD functionality to struct platform
  Experimental support for building without FSP code
