Subject: context_mgmt: Make cm_init_context_common public
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1634cae89d0e62853f6addbbaef8557893ee5613;p=project%2Fbcm63xx%2Fatf.git

context_mgmt: Make cm_init_context_common public

This function can be currently accessed through the wrappers
cm_init_context_by_index() and cm_init_my_context(). However, they only
work on contexts that are associated to a CPU.

By making this function public, it is possible to set up a context that
isn't associated to any CPU. For consistency, it has been renamed to
cm_setup_context().
