|
* 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 |
