2014-01-08char/cadence_uart: Simplify status generationPeter Crosthwaite1-25/+8
The status register bits are always pure functions of other device state. Move the generation of these bits to the update_status() function to simplify. Makes developing much easier as theres now no need to recheck status bits on all the changes to rx/tx fifo state.

2014-01-08char/cadence_uart: s/r_fifo/rx_fifoPeter Crosthwaite1-4/+4
Rename this field to match the many other uses of "rx". Xilinx docmentation (UG585) also refers to this as "RxFIFO".

2014-01-08char/cadence_uart: Fix reset.Peter Crosthwaite1-3/+4
Don't reset the uart as an init step. Register the reset function as a proper reset fn instead.

2014-01-08char/cadence_uart: Add missing uart_update_statePeter Crosthwaite1-0/+1
This should be rechecked on bus write accesses as such accesses may change the underlying state that generates the interrupt. Particular relevant for when the guest touches the interrupt status or mask.

2013-07-15char/cadence_uart: Fix reset for unattached instancesPeter Crosthwaite1-1/+3
commit 1db8b5efe0c2b5000e50691eea61264a615f43de introduced an issue where QEMU would segfault if you have an unattached Cadence UART. Fix by guarding the flush-on-reset logic on there being a qemu_chr attachment.
