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.
