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 |
