[PATCH v2 0/9] Add SMP bringup support for mt65xx socs

From: Yingjoe Chen
Date: Sat May 16 2015 - 03:59:23 EST


This series add SMP brinup support for mediatek SoCs. This is based
on v4.1-rc1.

There are 2 similar but different SMP bringup up methods on Mediatek
mt65xx and mt81xx. On MT8135 & MT8127, system boots with a trustzone
firmware. Others, like MT6589, doesn't have trustzone, and run kernel
directly in secure world.

Patch 1,2 are preparing patch, cleanup/fix in secondary_startup_arm
Patch 3~5 fix issues in mtk_timer(GPT) and enable arch timer support.
Patch 6,7 add support for cpu enable-method "mediatek,mt65xx-smp" and
"mediatek,mt81xx-tz-smp", which support Mediatek SMP bringup for non-TZ
and TZ platform.
Patch 8,9 finally enable SMP bringup for mt8135 and mt8127.

Changes in v2:
- Fix boot issue for THUMB2 kernel.
- Not enable GPT_CLK_EVT when setup to fix GPT spurious interrupt issue
- Change platsmp.c according to Matthias' suggestion
