[U-Boot-Users] Proposal for a make option to include an additional stand alone program directory

[Jeff Mann]

U-Boot Users:

I want to add a featue to the makefile configuration so that a user can
compile u-boot including a directory that gets compiled as a stand alone
program. I propose that users can enter a directory when configuring the
board, for example

make BOARD_config SA=my_stand_alone_prog_dir

so that the user can specify a directory to be compiled with u-boot. As
you can see, the SA directory is added to the mkconfig.mk file and then
included as a SUBDIRS when compiling. The purpose of this option is to
allow a user to *easily* include a directory containing a stand alone
program.

Is this an appropreate feature? Should this be done differently? After
implementing changes from your comments, I'll properly document this
option and send an appropreate patch.
