Subject: [PATCH v3 0/5] Add SMP bringup support for mt65xx socs
Date: Tue, 14 Jul 2015 13:18:26 +0800 [thread overview]
Message-ID: <1436851111-2369-1-git-send-email-yingjoe.chen@mediatek.com> (raw)
This series add SMP brinup support for MediaTek SoCs. This is based
on v4.2-rc1 and Matthias' next branch (for dts parts).
There are 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 enable arch timer support.
Patch 2,3 add support for cpu enable-method "mediatek,mt6589-smp" and
"mediatek,mt81xx-tz-smp", which support Mediatek SMP bringup for non-TZ
and TZ platform.
Patch 4,5 finally enable SMP bringup for mt8135 and mt8127.
Changes in v3:
- The first 2 patches in v2 are merged in v4.2-rc1.
- Patch 3~4 in v2 are moved to another series [1]
- platsmp.c changes based on Stephen's suggestion
- Change cpu enable-method name to "mediatek,mt6589-smp"
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
