a353e4a06f firmware: qcom: scm: Clean cold boot entry to export only the API
We dont need to export the SCM specific cold boot flags to the platform
code. Export only a function to set the cold boot address.

916f743da3 firmware: qcom: scm: Move the scm driver to drivers/firmware
Architectural changes in the ARM Linux kernel tree mandate the eventual
removal of the mach-* directories. Move the scm driver to
drivers/firmware and the scm header to include/linux to support that
removal.

4de43476fc ARM: qcom: Prep scm code for move to drivers/firmware
Add qcom prefix to functions, etc to create a unique name space for the
scm code as it gets ready to move out of qcom specific mach dir.

3d9b448bd2 ARM: qcom: Merge scm and scm boot code together
Put all scm related code into a single file as a first step in cleaning
up the scm interface to just expose functional behavior insteam of making
direct scm calls.

8684014d71 ARM: 8301/1: qcom: Use secondary_startup_arm()
On qcom platforms we always enter the kernel in ARM mode,
regardless of the kernel being compiled for THUMB mode. Use
secondary_startup_arm() to properly switch the mode to what the
kernel expects if required.

188611af42 ARM: qcom: Re-organize platsmp to make it extensible
This makes it easy to add SMP support for new devices by keying
on a device node for the release sequence. We add the
enable-method property for the cpus property to specify that we
want to use the gcc-msm8660 release sequence (which is going to
look for the global clock controller device node to map some
Scorpion specific power and control registers). We also remove
the nr_cpus detection code as that is done generically in the DT
CPU detection code.

cf1e8f0cd6 ARM: qcom: Rename various msm prefixed functions to qcom
As mach-qcom will support a number of different Qualcomm SoC platforms
we replace the msm prefix on function names with qcom to be a bit more
generic.

8fc1b0f87d ARM: qcom: Split Qualcomm support into legacy and multiplatform
Introduce a new mach-qcom that will support SoCs that intend to be
multiplatform compatible while keeping mach-msm to legacy SoC/board
support that will not transition over to multiplatform.

As part of this, we move support for MSM8X60, MSM8960 and MSM8974 over
to mach-qcom.
