SVN rev 221480 on 2011-05-05 03:42:04Z by adrian
Fix up the chipset checks for the AR5416 and later silicon.
The checks should function as follows:
* AR_SREV_<silicon> : check macVersion matches that version id
* AR_SREV_<silicon>_<revision> : check macVersion and macRevision match
the version / revision respectively
* AR_SREV_<silicon>_<revision>_OR_LATER: check that
+ if the chip silicon version == macVersion, enforce revision >= macRevision
+ if the chip silicon version > macVersion, allow it.
For example, AR_SREV_MERLIN() only matches AR9280 (any revision),
AR_SREV_MERLIN_10() would only match AR9280 version 1.0, but
AR_SREV_MERLIN_20_OR_LATER() matches AR9280 version >= 2.0 _AND_
any subsequent MAC (So AR9285, AR9287, etc.)
The specific fixes which may impact users:
* if there is Merlin hardware > revision 2.0, it'll now be correctly
matched by AR_SREV_MERLIN_20_OR_LATER() - the older code simply
would match on either Merlin 2.0 or a subsequent MAC (AR9285, AR9287, etc.)
* Kite version 1.1/1.2 should now correctly match. As these macros
are used in the AR9285 reset/attach path, and it's assumed that the
hardware is kite anyway, the behaviour shouldn't change. It'll only
change if these macros are used in other codepaths shared with
older silicon.
