* Memory entry used for the DEBUG_LL UART configuration, relative to
* start of RAM. See also uncompress.h and debug-macro.S.
*
* Note that using a memory location for storing the UART configuration
* has at least two limitations:
*
* 1. Kernel uncompress code cannot overlap OMAP_UART_INFO as the
* uncompress code could then partially overwrite itself
* 2. We assume printascii is called at least once before paging_init,
* and addruart has a chance to read OMAP_UART_INFO
