/*
 * 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
