16550A UART: RHR irq enable bit also masks the Rx timeout irq.
The "Rx timeout" (aka. Character Timeout Indication) has no separate mask bit in the IER register and according to the specs reading RHR is the only way to reset the irq. However on the hardware (tested on OMAP2 UART which is an extended 16550A) the RHR_IT bit in IER disables the irc, too. Linux bluetooth serial dongle driver for N800 depends on this behavior. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5239 c046a42c-6fe2-441c-8c8c-71466251a162
