Subject: [PATCH v5 0/5] ARM: rockchip: add smp functionality
Date: Tue, 22 Oct 2013 16:00:13 +0200 [thread overview]
Message-ID: <201310221600.13562.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 both a BQ Curie2 (rk3066a / dual core) and
on a Radxa Rock (rk3188 / quad core).
changes since v4:
- rebase on top of the recent rk3188 board support
- implement suggestion from Matt Sealey in moving the sram-limit from
marking reserved regions to marking available regions - hopefully
I got the usage right :-)
- remove __CPUINIT as suggested by Fabio Estevam
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
