bhnd nvram map: don't write "variable records written" to standard out by default

2018-05-19T18:15:41Z

Add -v (verbose) option for the developers. The rest of us derive no value from this information.

bhnd(4): Use the new BHND_CAP_BP64 capability flag to exclude DMA

2018-03-29T19:48:50Z

translations unsupported by the backplane.

bhnd(4): include a subset of the ChipCommon capability flags in bhnd_chipid;

2018-03-29T19:44:15Z

this provides early access to device capability flags required by bhnd(4) bus and bhndb(4) bridge drivers.

Add missing NULL checks when calling malloc(M_NOWAIT) in

bhnd_nv_strdup/bhnd_nv_strndup. If malloc(9) failed during initial bhnd(4) attach, while allocating the root NVRAM path string ("/"), the returned NULL pointer would be passed as the destination to memcpy(). Reported by: Ilja Van Sprundel

siba(4): Ignore disabled per-core address match entries.

2018-02-12T19:36:26Z

Previously, the address regions described by disabled admatch entries would be treated as being mapped to the given core; while incorrect, this was essentially harmless given that the entries describe unused address space on the few affected devices. We now perform parsing of per-core admatch registers and interrupt flags in siba_erom, correctly skip any disabled admatch entries, and use the siba_erom API in siba_add_children() to perform enumeration of attached cores.

bwn(4): migrate bwn(4) to the native bhnd(9) interface, and drop siba_bwn.

2018-02-05T23:38:15Z

- Remove the shim interface that allowed bwn(4) to use either siba_bwn or bhnd(4), replacing all siba_bwn calls with their bhnd(4) bus equivalents. - Drop the legay, now-unused siba_bwn bus driver. - Clean up bhnd(4) board flag defines referenced by bwn(4).

bhnd_chipc(4): Fix leak of child device ivars by explicitly deleting

any children prior to detach. With the newbus child deletion ordering changes introduced in r307518, parent devices are now detached (and their driver set to NULL) prior to detaching and deleting child devices; child-related bus methods (e.g. BUS_CHILD_DETACHED, BUS_CHILD_DELETED) are no longer be dispatched to the parent device driver after it returns 0 (success) from DEVICE_DETACH.
