To wake a core from wfi interrupts must be enabled, in some cases they
may not be and so we can lock up here. Unconditionally enable interrupts
before wfi and then restore interrupt state.

While it would be useful to have a device tree based build, the
required components are not in place yet, so support just a simple
statically defined configuration to begin with.

related to ti-sci so these are only stubs for now.

This library will be used to properly set up mappings from different
bootloaders at different exception levels. It ensures that memory mapped
devices such as UARTs are still accessible and memory regions have the
correct access permissions.

Because there is no BL2, BL31 must determine the entrypoint and memory
location of BL32 and BL33 on its own.
BL32_BASE and PRELOADED_BL33_BASE will be set in the corresponding board
makefile. We also allow a DTB address to be specified for cases when BL33
is a Linux image.
NOTE: It is possible to pull in this information from device tree as
well, however libfdt does not contain the required hooks to make this
happen at this point in time.

ti: k3: common: Add platform core management helpers
The K3 family of SoCs has multiple interconnects. The key interconnect
for high performance processors is the MSMC3 interconnect. This is
an io-coherent interconnect which exports multiple ports for each
processor cluster.
Sometimes, port 0 of the MSMC may not have an ARM cluster OR is isolated
such that the instance of ATF does not manage it. Define macros
in platform_def.h to help handle this.
