    [if's replaced by ifdef's.]
    
    While the BLOB boot loader doesn't support it, there are two others,
    UBOOT and Logic's LOLO, that will initialize the SDRAM controller such
    that the memory appears as a contiguous region.  This layout to be
    required for WinCE and, thus, is the default for these loaders.  The
    memory organization had been optimized for discontiguous blocks.  Now,
    it supports a default mode that is compatible with all of the
    bootloaders as well as options to optimize for either contiguous or
    discontiguous models.
    
    Withing, there is also a slight change to the way that the DEBUG_LL
    macros select the UART address.  Now it uses immediate constants
    exclusively.
