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:
