What's in sh-2.6.git for 2.6.33?
This is the current set of changes bound for 2.6.33. There's quite a lot of random bits with nothing particularly exciting standing out.
There's been quite a bit of cache flushing rework for newer parts with relatively more complex and configurable cache features/topologies, some overhauling of the PMB code (with the bulk of that carrying over to 2.6.34), more SH-Mobile enhancements (SDHI, R-standby, etc.).
Beyond that, there's also a migration from oprofile to perf events, with support for perf counters in all SH-4A parts for the first time, as well as the legacy SH7750S/SH7091 migration.
And some more chainsawing and shuffling around of code so we can start supporting ARM-based SH-Mobile CPUs with all of the existing infrastructure, too.
The tree is at:
