which contain 'standard' com- and lpt-type ports. Some of these present
as PCI simple-communications/serial or simple-communications/parallel
devices, but many do not. (Additionally, there is no document that I can
find that describes the "specific well-konwn register-level" description
of how the 'standard' devices' config space headers shold work.) Eventually,
some of the devices driven by this code should become simple pci attachments
for the 'lpt' and 'com' drivers, but that requires solid documentation.
the BAR-printing function to print a name for the register, factor out
a common register-bits function which can handle the fact that type 2
headers have a different size than is usual, and actually do something
useful with the rest of the bits in the type 2 header.
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.
used in the SMC EtherPower II.
Media control isn't yet supported, due to some MII infrastructure
problems which I hope to address soon. This isn't a huge deal, since
the PHY defaults to auto-negotiate mode.
Also, the device just programs the multicast hash table to accept all
multicast, to avoid a hardware bug that causes the multicast address
filter to lose in 10Mb/s mode. This bug will be fixed in a more sane
way once the media control issues are dealt with.
