[U-Boot] [PATCH v3 04/36] board: samsung: refactor host programs

[Masahiro Yamada]

Some Samsung boards have their own tools under board/samsung/<board>/tools/.
This commit refactor more makefiles with "hostprogs-y".

Note1:
Samsung boards have tools under board/samsung/<board>/tools/
and have tools/mkexynosspl.c too.
It is inconsistent, so we should choose the appropriate
directory in which Samsung-specific tools are stored.

Note2:

I marded TODO item in board/samsung/origen/Makefile.

Samsung engineers, I hope you will fix the root cause of the warning.

 # omit -O2 option to suppress
 #   warning: dereferencing type-punned pointer will break strict-aliasing rules
 #
 # TODO:
 # Fix the root cause in tools/mkorigenspl.c and delete the following work-around
 $(obj)/tools/mkorigenspl: HOSTCFLAGS:=$(filter-out -O2,$(HOSTCFLAGS))
