This is a collection of misc cleanups I have accumulated when working on some
recent OpenRISC projects.
The patch themes:
- Sparse warning cleanups
- Removal of dead code
- Emergency debug fixups in head.S
- Support for gcc machine instruction flags
- defconfig updates for litex
I have tested these patches when verifying the glibc port by running the glibc
test suite.
Changes since v2:
- Don't enabled class II instructions by default
Changes since v1:
- Fix if/elif issue in emergency print fixes pointed out by Samuel Holland
