[PATCH 6/7] arm: mmp&dove: modify tauros2_init call

Hi Chao

When making changes to Dove, or any other Orion system, please could
you CC: the orion maintainers:

ARM/Marvell Dove/Kirkwood/MV78xx0/Orion SOC support
M:      Jason Cooper [off-list ref]
M:      Andrew Lunn [off-list ref]
L:      linux-arm-kernel at lists.infradead.org (moderated for non-subscribers)
S:      Maintained
F:      arch/arm/mach-dove/
F:      arch/arm/mach-kirkwood/
F:      arch/arm/mach-mv78xx0/
F:      arch/arm/mach-orion5x/
F:      arch/arm/plat-orion/

Does this also affect Armada 370 and Armada XP SOC? I've no idea what
cache it uses.

Thanks
	Andrew

It will impact Armada 370. The patch will make the user has choice to
enable extra features of tauros2
I have searched the code, only dove will use tauros2_init, and the
tauros2 default has its extra features off, so i directly pass 0x0 for
dove

It will impact Armada 370.
Then please keep Gregory Clement [off-list ref]
in the loop as well.

The patch will make the user has choice to
enable extra features of tauros2
I have searched the code, only dove will use tauros2_init, and the
tauros2 default has its extra features off, so i directly pass 0x0 for
dove
Can you recommend any benchmark tools, to see if its worth turning on
these features? Sebastian Hesselbarth is doing a lot of work on Dove
at the moment, so might be interested in investigating this.

Thanks
	Andrew

As far as I know it wouldn't impact the Armada370 as it use an other L2
called Aurora. We are currently working on it to submit it really soon.
The ArmadaXP also use the Aurora L2 cache controller.
