12 * Memory entry used for the DEBUG_LL UART configuration, relative to
13 * start of RAM. See also uncompress.h and debug-macro.S.
14 *
15 * Note that using a memory location for storing the UART configuration
16 * has at least two limitations:
17 *
18 * 1. Kernel uncompress code cannot overlap OMAP_UART_INFO as the
19 * uncompress code could then partially overwrite itself
20 * 2. We assume printascii is called at least once before paging_init,
21 * and addruart has a chance to read OMAP_UART_INFO
