[PATCH v5 0/5] Add SMP bringup support for mt65xx socs

From: Yingjoe Chen
Date: Fri Oct 02 2015 - 11:19:56 EST


This series add SMP brinup support for MediaTek SoCs. This is v5 and
is based on v4.3-rc1.

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 v5:
- Fix dts error
- Add Rob's Ack tag.

Changes in v4[3]:
- rebase to v4.3-rc1
- Reserve trustzone bootinfo memory area in device tree.

Changes in v3:
- v3 in [1]
- The first 2 patches in v2 are merged in v4.2-rc1.
- Patch 3~4 in v2 are moved to another series [2]
- 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
