Subject: [PATCH v4 0/6] ARM: rockchip: add smp functionality
Date: Mon, 29 Jul 2013 15:10:31 +0200 [thread overview]
Message-ID: <201307291510.31679.heiko@sntech.de> (raw)
This series enables the use of the additional cores on Rockchip
Cortex-A9 SoCs.
To achieve this, add the scu, the needed sram and power-management-unit.
Tested on a rk3066a (dual core) by me and on a rk3188 (quad core)
by Ulrich Prinz.
(Note: rk3188 support in general needs additional upcoming patchsets)
changes since v3:
- address comments from Rob Herring:
- split the gathering of the reserve-data into a separate loop
- spelling and style fixes
- first patch only included for reference, already part of the
char-misc git tree
changes since v2:
- rework the sram allocation following the suggestion from Philipp Zabel
changes since v1:
- add reserved block feature for mmio-sram, to not use two logical
sram nodes
- the sram content is kept intact while the device is running, so
copying the trampoline is only needed once
Heiko Stuebner (6):
misc: sram: fix error path in sram_probe
misc: sram: add ability to mark sram sections as reserved
ARM: rockchip: add snoop-control-unit
ARM: rockchip: add sram dt nodes and documentation
ARM: rockchip: add power-management-unit dt node
ARM: rockchip: add smp bringup code
