[ECOS] IXP 424 UART problem

Hi,

We are running redboot on IXP 425 platform. The IXP425 has a known bug
that when the UART break indicator (fourth bit of LSR) is de-asserted,
it is possible for the UART to detect a start bit and receive an
incorrect 0xFF byte. And this bug is not fixed.  

So when this incorrect 0xFF byte received the bootloader goes in
blocking read mon_read_char() and the bootloader gets stuck up there. 

Does anybody have any workaround for this? 

Regards

Jamal
