This is a rebased version of this series which is ready for broader testing. I'd especially appreciate testing from those of you with AM35x platforms.

Currently, our SoC detection is based on SoC family detection (using die ID) and the presence of specific IP blocks (or feature.)

This series begins the separation of the SoC family detection and specific IP detection by completely removing IP detection from the SoC family detection (cpu_is_*.)

Applies on top of v3.4-rc4, boot tested on AM3517 EVM.

Your series applied and booted without issue until the point that pm_idle is called. At that point it hung because its doing a wfi and not getting an interrupt to wake up back up. That's expected behaviour so your patches are good (IMHO) but I need to finish and submit a new version of my patches to fix that issue.

For the benefit of others wanting to test this:

You have to use 'nohlt' on the cmdline on AM35x in order to avoid WFI and the wakeup problems that are still being worked on.

Oops, yes. I meant to add that and say that my am3517evm boots fine with your patches and 'nohlt' on the cmdline. I'm using omap2plus_defconfig with CONFIG_TI_DAVINCI_EMAC enabled.
