v3 Geode cs5536 UART2 wrongly configured
|Reported by:||edwin_beasant@…||Owned by:||hailfinger|
|Component:||coreboot||Keywords:||serial com2 geode cs5536|
|Patch Status:||patch has been committed|
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.
