Cover letter [U-Boot] [PATCH v3 0/4] sun7i: PSCI enhancements

Hi,

Quoted 1 line · Ian Campbell

I've applied #1 and #3. I'd like to hear from Hans on the v0.2 stuff.

I've no real opinion on this, I do NOT like the introduction of a third version of the i2c / rsb and axp code (we already have both a u-boot and a kernel version to maintain of both).

Given that and rumors I've heard of a new PSCI version which may make things like shutdown optional, I would prefer to wait for such a new PSCI version and jump directly to that.

But ultimately I defer to Ian here, so Ian whatever you say goes :)

Regards,

Hans

Also, the other patches are touching generic arm code, so ought to be CC-d to (and perhaps go via) the core ARM maintainer (Albert Aribaud).

IMHO it would be better if the common code changes involved platform-selectable #ifdef's for enabling v0.1 and v0.2, to allow platforms to opt-in to v0.2 support.

This adds CPU offlining and PSCI v0.2 support. Changes since v2:
- add more comments to psci_fiq_enter (patch 1)
- rebase over u-boot-sunxi/next

See patches for further details.
