    omap: Use a memory address for storing the debug port info instead of UART1 scratchpad · 96554d70

    This removes the dependency to the UART1 being available for storing
    the debug configuration in uncompress.h. This will simplify the
    DEBUG_LL UART configuration for boards that may not have UART1, or
    have an external UART as it requires only one mapping for DEBUG_LL.
    
    The patch has a few limitations. Basically now we're assuming that
    the kernel uncompress code won't overlap with OMAP_UART_INFO. We also
    assume the printascii is called at least once before paging_init in
    order for addruart to have a chance to read the UART setup from
    OMAP_UART_INFO.
    
    As suggested by Cyril Chemparathy <cyril@ti.com>,
    Vikram Pandita <vikram.pandita@ti.com> and
    Kevin Hilman <khilman@deeprootsystems.com>. Based on an earlier
    patch posted for Davinci by Cyril Chemparathy <cyril@ti.com>.
