On machines with huge amount of swap and high IO activity,
watchdogd(8) may wait for a swap memory longer than timeout and
sometimes fires.

802.11n router.
The flash layout defaults to a 1 MiB section for the kernel so I'm trying
very hard to squeeze a minimialistic (LZMA compressde) kernel image into
that.
I've verified that it boots through to single user mode fine.
Issues:
* USB doesn't yet work as a module - I need to add something else to the
USB AR71xx build before that will work.
* There's no switch PHY support - but for now it quite happily behaves
as a useful dumb switch out of the box. Phew.
* Since a previous flash attempt trashed my radio configuration block,
I haven't yet verified whether the wireless works correctly.
I'll test that out shortly (read: once I re-calibrate the board somehow.)
Thanks to ray@ and the zrouter project for doing some of the initial
hard work in figuring out how to bring this board up.
restructuring of the driver. I've tried to preserve the other silicon
workarounds that we've added over the years, but haven't had a chance
to extensively test on other hardware. On my AT91RM9200 with 30MHz/1
wire/64 block transfers, I've been able to go from ~.66MB/s to
2.25MB/s in the simple tests I performed, almost a 3.5x improvement.
This cuts the boot time almost in half when everything else goes
right (timed from rtc message to login: prompt).

The comparison assumes maxFirstepLevel is a count, rather than a maximum
value. The array is 3 entries in size however 'maxFirstepLevel' is 2.
This bug also exists in the AR5212 HAL.
MPSAFE.
- Preallocate a full set of QCBs during attach rather than allocating new
ones on demand to avoid allocations in the I/O path.
- Remove the explicit bus space tag/handle and use bus_*() on the
relevant 'struct resource' instead.
- Defer logical drive probing to an intrhook.
- Fix ida_detach() to detach and delete child devices (logical drives).
- Update the DMA handling to support EINPROGRESS by moving the work to
submit a mapped request into the bus_dma callback routine as well as
add support for freezing the queue when EINPROGRESS is encountered.

explicltly enable that. The driver chose to use 60MHz / 2 (30MHz)
most of the time rather than 60MHz / 4 (15MHz) based on the Linux
driver of the time. This pushes the spec a little in order to not
suffer the penalty of running at 15MHz. However, when other bus
masters are active in the system, and the user tries 4-wire mode, the
internal bus arbitration would fail with data loss as a result.

pthread_suspend_all_np() may have already suspended its parent thread.
Add locking code in pthread_suspend_all_np() to only allow one thread
to suspend other threads, this eliminates a deadlock where two or more
threads try to suspend each others.
Terasic DE-4 board. Allow LED configuration to be set using loader
tunables, not just from userspace, and preconfigure LED 8 as a kernel
heartbeat. For now, this is a Nexus-attached, BERI-only driver, but it
could be used with other hard and soft cores on Altera FPGAs as well, in
principle.

This allows EEPROM-less NICs on the AR7241 PCIe bus to be correctly
initialised.
Tested:
* AP91 (AR7240+AR9285) - the existing board support didn't break;
* AP99 (AR7241+AR9287) - this fixed the configuration of the AR9287 PCI.

Similarly, filter out any -std=xxx options that aren't supported.
