Hi list,
This is the second version of my patchset for supporting PSCI (i.e. second core bringup) on R528/T113-s#, incorporating most of the feedback from Andre.
I do not expect the final two patches in this series to be winners yet. There's still some back-and-forth going on to sync them up with an anticipated v2 of Andre's patchset for R528 support (on which this work depends). My v2 is being sent now mostly just to smoothen that.
However, the first 3 patches in this series ARE meant to be reviewed seriously: the refactoring is totally independent of the R528 effort, and I see no reason to wait for the R528 stuff to be nailed down to get started reviewing them.
Going forward, any more changes will most likely be form over function, so aggressive testing of the whole 5-patch series -- on sunxis old and new -- is nonetheless very valuable at this point. :)
Changes v1->v2: - Power clamp is now adjusted ONLY on sun{6,7}i, H3, R40. The previous version was mistakenly doing this EXCEPT on those machines. - Flattened sunxi_power_switch() into sunxi_cpu_set_power() for simplicity's sake. - Moved the "power clamp is not NULL" conditional into sunxi_cpu_set_power(). - Removed unnecessary H6 special-case, since H6 is actually ARM64. - Renamed SUNXI_CPUX_BASE to SUNXI_CPUCFG_BASE, to mirror expected changes in Andre's v2 of the R528 series (we decided against using a new name for this block). - Removed sunxi_cpucfg_reg struct, and stopped using the PRCM struct in psci.c.
Cheers, Sam
