The main changes needed are:
1) pass address and IRQ information from aubus (auspi uses interrupts)
2) all Au1550 PSC protocols have the same status and register bits
for enable, so clean that up (clock registers could be different)
3) improve timeout logic on enable (a fixed delay isn't good enough)
4) make aupsc_print return QUIET, as it is annoying to see messages
for unconfigured protocols. This whole mechanism should be re-
engineered, to either use indirect configuration or provide more
detailed board-driven configuration. A comment to that effect is
placed in the source.
This is shown to work on DBAU1550.
a sample driver for the TI TMP121 temperature sensor. This has been
moderately tested on Au1550, and it is not enabled in sys/conf (yet). So
the change is harmless at worst, and useful at best.
Alchemy Au1550 bus driver forthcoming, along with a driver for SPI flash
devices, such as found on the Meraki Mini
This development was partially funded by the Champaign-Urbana Community
Wireless Network Project.
Note that there are some MD-specific SPI drivers that could probably be
made MI under this new framework.
assigned to request 0. With this change, ethernet interrupts are assigned
to req1, seperately from req0. This potentially gives better performance
by shortening the list of handlers walked somewhat.
Brought up on tech-kern@ some ~2 months ago, didn't seem to be an
objection; brought up again recently and no objection either... this is
not too intrusive and I've been running with this for a while.
structures can thus be misaligned for DMA when declared on stack.
The current atapi code accepts the misaligned dma's only screw's them up.
This small patch disables DMA for the rare transactions that are
misaligned. Note that all bulk-transfers are aligned due to page sizes.

SMBios detection and mapping to bios32.c, also from OpenBSD (for now this
is only compiled in if ipmi(4) is configured). The sensors and watchdog are
accessible though envsys(4).
Works on i386; some work is needed on amd64 to access the BIOS. It would
eventually work on Xen if the SMBios is accessible (to be tested).
and if ALTQ and pf are both enabled, it leads to compile errors. So,
change all tests for ALTQ to ALTQ_NEW, which won't be defined.
This allows simultaneous compilation of pf and ALTQ and is a temporary
measure before the peter-altq brach is merged.
Tested and approved by Peter Postma.
driver uses the board's DMA system, uses the machine-independent WD33C93
driver, works on NetBSD/acorn26, and doesn't share a name with six other
machine-dependent SCSI drivers. Not tested on acorn32, but it seems to
work tolerably well on my A540.
