stuff necessary to separate out AR5312 from AR5315. This includes:
1) rework of arbus IRQs, so that IRQs are now seperately specified
as either MISC or CPU irqs
2) move board/chip-specific addresses into chip-dependent file
3) unencumber argpio from ar5312 specifics, using properties to pass
details such as reset-pin and sysled-pin.
4) an option to select which WiSoC is to be configured is provided.
AR5315 support should be forthcoming shortly now.
This allows us to convert aucom to just another com attachment, and cleanup
some code in the com_arbus.c.
Additionally, we use a common com_cleanup routine rather than having a
zillion copies of it in the attachment points.
This has been tested on a number architectures, and it has been shown to get
close to comparable performance when COM_REGMAP is defined, and comparable
when it is not defined.
Approved by core@. Fixes PR port-evbmips/32362.
so that when it is pressed the default reset button action (currently board
reset, no change to data in flash) is taken.
While here, remove the AR531X generic config, because it just doesn't make
sense.
Additionally, do not fail if no RTC is present, as not all boards have one.
Malta now uses the common dev/ic/mc146818.c code as much as possible, reducing
local "custom" code. These malta changes are *untested*, as I do not have
a Malta board to test with. If someone would please test them and get back to
me, I'd appreciate it!
Some devices work (an, wdc), while others do not (ne, wi).
However, the bus is useful enough that it makes sense to go ahead and
enable it. Maybe other folks can help me debug the rest of the problems.
and serial ports are supported, and the system appears stable with an NFS
mounted root. An earlier version of the code was reviewed by simon@, but it
has since had numerous improvements and cleanups.
At the moment, only AR5312 is known to work, but I suspect AR2313 will work
as well. Later 2315/2316 parts are substantially different, and are not yet
supported. Wifi and Marvell switch support found on some designs are not yet
supported.
Platforms known to include AR5312 include Senao Aries 2 (AP5054) and Netgear
WGU624.
in the config are left intact, though.
Add a PMAP-driven bus_space for access to upper memory, instead of using
wired entries.
Convert aupci to use said bus_space -- no measured performance impact.
PCI idsel and irq routing (later).
Various cleanup/rototilling to remove hardcoded pb1000 references.
