17 * Memory entry used for the DEBUG_LL UART configuration, relative to
18 * start of RAM. See also uncompress.h and debug-macro.S.
19 *
20 * Note that using a memory location for storing the UART configuration
21 * has at least two limitations:
22 *
23 * 1. Kernel uncompress code cannot overlap OMAP_UART_INFO as the
24 * uncompress code could then partially overwrite itself
25 * 2. We assume printascii is called at least once before paging_init,
26 * and addruart has a chance to read OMAP_UART_INFO
