and the Z8530 drivers used the I/O address as a quick and dirty way to determine which channel they operated on, but formalizing this by introducing iobase is not a solution. How for example would a driver know which channel it controls for a multi-channel UART that only has a single I/O range? Instead, add an explicit field, called chan, to struct uart_bas that holds the channel within a device, or 0 otherwise. The chan field is initialized both by the system device probing (i.e. a system console) or it is passed down to uart_bus_probe() by any of the bus front-ends. As such, it impacts all platforms and bus drivers and makes it a rather large commit. Remove the use of iobase in uart_cpu_eqres() for pc98. It is expected that platforms have the capability to compare tag and handle pairs for equality; as to determine whether two pairs access the same device or not. The use of iobase for pc98 makes it impossible to formalize this and turn it into a real newbus function later. This commit reverts uart_cpu_eqres() for pc98 to an unimplemented function. It has to be reimplemented using only the tag and handle fields in struct uart_bas. Rewrite the SAB82532 and Z8530 drivers to use the chan field in struct uart_bas. Remove the IS_CHANNEL_A and IS_CHANNEL_B macros. We don't need to abstract anything anymore. Discussed with: nyan Tested on: i386, ia64, sparc64
