Pete says the AMD Alchemy UART is just different enough to be hard to handle in the 8250 and so the driver is just an ugly chainsawed version of the 8250.c Most of the difference seems to be the PCI stuff, that has been removed and the access method. Shouldn't we have a driver for the chip and one driver for each access method (isa,pci,...). The access method should handle register access and the bus abstraction.I have a lot of problems with the au1x00 serial driver, because I use it together with a PCMCIA serial port card. Michael |
