o Introduce PUC_PORT_TYPE_UART so that we can attach to uart(4), o Introduce port sub-types (eg PUC_PORT_UART_NS8250, PUC_PORT_UART_Z8530) to handle different hardware and determine resource sizes. o Introduce two new IVARs: PUC_IVAR_SUBTYPE and PUC_IVAR_REGSHFT. Both are used by uart(4) to get sufficient information to talk to the HW. o Introduce PUC_FLAGS_ALTRES to tell puc(4) to try memory mapped I/O if I/O port space cannot be allocated, or vice versa. o Have ports of type PUC_PORT_TYPE_COM attach to uart(1) if attaching to sio(4) fails (due to not having the sio driver). o Put struct puc_device_description in struct puc_softc instead of having a pointer to a device description in the softc. This allows us to create device descriptions on the fly without having to use malloc() or otherwise have them staticly defined. o Move puc_find_description() from puc.c to puc_pci.c as it's specific to PCI. o Add EBUS and SBUS frontends for use on sparc64. Note that the P in puc stands for PCI, so we kinda mess things up here. It's too soon to worry about it though. We'll know what to do about it in time. NOTE: This commit changes the behaviour of puc(4) to not quieten the device probe and attach for child devices. The uart(4) driver provides additional device description that is valuable to have.
