In fact, linux has startup normally, but UART dies, we can telnet the board and

check the interrupts:

root@roc-desktop:~/develop/svn/uclinux-dist# telnet 10.99.29.118

Trying 10.99.29.118...

Connected to 10.99.29.118.

BFIN_UART_RX is always 0 no matter how many bytes are inputed in console.

When disabling DMA mode for UART, all get normal:
