The sinfo function declared in sinfo_instance.h creates a static sinfo
object instance and returns a pointer to the caller.
- kernel timer and platform support to use sinfo() function to
instantiate sinfo object
- address and size of the base-hw RAM region via the sinfo API
- log_status() function in sinfo API
Instead of holding SPEC-variable dependent files and directories inline
within the repository structure, move them into 'spec' subdirectories
at the corresponding levels, e.g.:
repos/base/include/spec
repos/base/mk/spec
repos/base/lib/mk/spec
repos/base/src/core/spec
...
Moreover, this commit removes the 'platform' directories. That term was
used in an overloaded sense. All SPEC-relative 'platform' directories are
now named 'spec'. Other files, like for instance those related to the
kernel/architecture specific startup library, where moved from 'platform'
directories to explicit, more meaningful places like e.g.: 'src/lib/startup'.
Fix#1673
