All of the instances of imx*_boot_save_loc() do exactly the same thing with the only difference being SoC-specific imx*_get_boot_source call. Convert the code into a generic function taking function pointer to perform SoC specific bits.
Signed-off-by: Andrey Smirnov <andrew.smir...@gmail.com> --- Sascha: This is my second take on the patch we discussed in [thread1]. It saves a whole bunch of boilerpalte code while keeping all function names greppable. Hopefully this is good enough to be merged.
