    ppc4xx: Remove superfluous dram_init() call or replace it by initdram() · bbeff30c

    Historically the 405 U-Boot port had a dram_init() call in early init
    stage. This function was still called from start.S and most of the time
    coded in assembler. This is not needed anymore (since a long time) and
    boards should implement the common initdram() function in C instead.
    
    This patch now removed the dram_init() call from start.S and removes the
    empty implementations that are scattered through most of the 405 board
    ports. Some older board ports really implement this dram_init() though.
    These are:
    
    csb272
    csb472
    ERIC
    EXBITGEN
    W7OLMC
    W7OLMG
    
    I changed those boards to call this assembler dram_init() function now
    from their board specific initdram() instead. This *should* work, but please
    test again on those platforms. And it is perhaps a good idea that those
    boards use some common 405 SDRAM initialization code from cpu/ppc4xx at
    some time. So further patches welcome here.
