Various updates to most of the smbus(4) drivers: - Use printf() and device_printf() instead of log() in ichsmb(4). - Create the mutex sooner during ichsmb(4) attach. - Attach the interrupt handler later during ichsmb(4) attach to avoid races. - Don't try to set PCIM_CMD_PORTEN in ichsmb(4) attach as the PCI bus driver does this already. - Add locking to alpm(4), amdpm(4), amdsmb(4), intsmb(4), nfsmb(4), and viapm(4). - Axe ALPM_SMBIO_BASE_ADDR, it's not really safe to write arbitrary values into BARs, and the PCI bus layer will allocate resources now if needed. - Merge intpm(4) and intsmb(4) into just intsmb(4). Previously, intpm(4) attached to the PCI device and created an intsmb(4) child. Now, intsmb(4) just attaches to PCI directly. - Change several intsmb functions to take a softc instead of a device_t to make things simpler. 2007-01-11 19:56:24 +00:00			`#define PCI_HST_CFG_SMB 0xd2 /* Host Configuration */`
