allocation was passed up to nexus. Now, we probe sysresource objects and
manage the resources they describe in a local rman pool. This helps
devices which attach/detach varying resources (like the _CST object) and
module loads/unloads. The allocation/release routines now check to see if
the resource is described in a child sysresource object and if so,
allocate from the local rman. Sysresource objects add their resources to
the pool and reserve them upon boot. This means sysresources need to be
probed before other ACPI devices.
Changes include:
* Add ordering to the child device probe. The current order is: system
resource objects, embedded controllers, then everything else.
* Make acpi_MatchHid take a handle instead of a device_t arg.
* Replace acpi_{get,set}_resource with the generic equivalents.

a boot-bus controller the i2c are said to not be a PCF8584). Similar to the
SUNW,envctrl devices, onboard slaves for monitoring fans, temperatures and
such hang off of these i2c devices. But there's also stuff like EEPROMs
housing the hostid of the system and the boards usally have a connector to
add custom slave devices (on CP1500 there's actually a second PCF8584 with
its own I2C bus for these).
This driver already works fine but I'm not yet sure if access to the slave
devices on CP1400/CP1500 marked as "reserved for factory use" in the docs
should be blocked (most likely these are the voltage controllers wich aren't
meant to be controller by software and even not by the firmware). Once the
issues with polled mode are fixed in the common pcf(4) part in pcf.c, this

- In subr_ndis.c, my_strcasecmp() actually behaved like my_strncasecmp():
we really need it to behave like the former, not the latter. (It was
falsely matching "RadioEnable", which defaults to 1 with "RadioEnableHW"
which the driver creates itself and to 0, because we were using
strlen("RadioEnable") as the length to test. This caused the radio to
always be turned off. :( )
- In if_ndis.c, only set IEEE80211_CHAN_A for channels if we actually
set any IEEE80211_MODE_11A rates. (ieee80211_attach() will "helpfully"
add IEEE80211_MODE_11A to ic_modecaps for you if you initialize any
802.11a channels. This caused "ndis0: 11a rates:" to erroneously be
displayed during driver load.)
- Also in if_ndis.c, when using TESTSETRATE() to add in any missing 802.11b
rates, remember to OR the rates with IEEE80211_RATE_BASIC, otherwise
comparing against existing basic rates won't match. (1, 2, 5.5 and
11Mbps are basic rates, according to the 802.11b spec.) This erroneously
cause 11Mbps to be added to the 11b rate list twice.
