If anyone has any objections, please let me know. ------------------ From: Mischa Jonker commit 6eda477b3c54b8236868c8784e5e042ff14244f0 upstream. The Synopsys APB DW UART has a couple of special features that are not in the System C model. In 3.8, the 8250_dw driver didn't really use these features, but from 3.9 onwards, the 8250_dw driver has become incompatible with our model.
