* 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
