RISC-V Patches for the 5.20 Merge Window, Part 2
There's still a handful of new features in here, but there are a lot of
fixes/cleanups as well:
* Support for the Zicbom for explicit cache-block management, along with
the necessary bits to make the non-standard cache management ops on
the Allwinner D1 function.
* Support for the Zihintpause extension, which codifies a go-slow
instruction used for cpu_relax().
* Support for the Sstc extension for supervisor-mode timer/counter
management.
* Many device tree fixes and cleanups, including a large set for the
Canaan device trees.
* A handful of fixes and cleanups for the PMU driver.
----------------------------------------------------------------
These all pass for me, but they do require some sparse patches that I just
posted to handle the new ISA strings. There are a handful of warnings, but
they're all in various stages of being fixed and the only one that's
reproducing locally for me is the bluetooth issue that's not related to any of
these.
