Patchstatus:  patch needs review           |  
 The UART2 on the AMD cs5536 is incorrectly configured in two places in v3
 code and also in v2.
 GPIO lines 4 and 3 are swapped and also incorrectly put in IR mode receive
 (compound fault).
 This patch corrects the v3 late configuration and the v3 and v2 early
 (stage1/cache as ram) mis-configuration of UART2 to addres 0x3f8 not the
 standard 0x2f8 for COM2.
