When ARM core resumes from low-power mode where losing power, for my
example: CA-9 MPCore resumes from Dormant/Shutdown, we have to
reinitialize components like L2 Cache, GIC and SCU to bring system
back to work.

Do you really need to do a re-init function for L2.
Look at the OMAP code, You just need to restore the configuration
registers and that's it. And the save can be done only once because
these are configuration register which won't change in the live system.
BTW, if it works for rest of the architectures, then I don't have
objection on these patches.
These patches definitely avoid more code getting added. :)
