Hello,
Following the feedback I go on the patch "ARM: mvebu: Enable SCU
Speculative linefills to L2 for Armada 375/38x" :
http://thread.gmane.org/gmane.linux.ports.arm.kernel/335961/focus=335993
I take the opportunity of adding new functions in smp_scu.c to
centralize the other access done on the SCU register from C file in
this file.
The first patch is a preliminary clean-up in smp_scu.c.
The second and the third patches add functions to manipulate the SCU
control register.
The forth patch use the new scu_spec_linefills_enable()
function. Enabling SCU Speculative linefills to L2 for Armada 375/38x
was the reason of this series.
The last patch removed a direct access to the SCU register by an
access through the new scu_standby_enable() function. For this one I
have just checked that the kernel can be built using the
imx_v6_v7_defconfig config, but I didn't test it on an imx6 hardware.
Thanks,
Gregory CLEMENT (4):
ARM: smp_scu: Used defined value instead of literal constant
ARM: smp_scu: Add the enable speculative linefills operation
ARM: smp_scu: Add the enable standby operation
ARM: imx6q: Use the new function scu_standby_enable()
