[PATCH] fix cpm_uart driver for PQ1...

[David Jander]

Hi,

This patch fixes the following three problems:

1. Memory mapping virtual<-->dma is broken in the case that 
CONFIG_CONSISTENT_START > CPM_ADDR.

2. SCC uart sends a break sequence each time it is stopped with the 
CPM_CR_STOP_TX command. That means that each time an application closes the 
serial device, a break is transmitted.

3. Implemented default BRG routing for PQ1 (in the same sense as it is done 
for PQ2).

Regards,

David.
