    [POWERPC] Make more OF-related bootwrapper functions available to non-OF platforms · 08464712
    David Gibson 提交于
    Commit 2e601613 split up
    arch/powerpc/boot/of.c so that some OF functions can be used on
    platforms that don't want to use the overall OF platform boot code.
    This is useful on things like PReP which can have an OF implementation
    which is useful for debugging output, but inadequate for booting.
    
    However, that commit didn't export quite enough things to make a
    usable OF console on a non-OF system.  In particular, the device tree
    manipulation performed to initialize the OF console code must
    explicitly use the OF device tree, rather than the flattened device
    tree, even if the system is otherwise booting using a flattened device
    tree.  This makes it so.
