This identation fix was done with the following command:

find . -type f -regextype posix-extended -iregex ".*(\.c|\.h|\.vhd)" | \
	xargs sed -i 's/  /\t/g'

minicircuits gain ctrl testbench added

minicircuits gain ctrl hdl added as RFFE submodules
swap RF channels hdl added as RFFE submodule

I have accidentally commited changes made into
the submodule hdl/ip_cores/general-cores. That
created a unpublished commit that was unable to
reach. Now, the submodule points to a valid commit
and no longer references the original project,
but a fork from it hosted in github.
