thorpej | For CIA/Pyxis and Tsunami/Typhoon/Titan, save the firmware's idea of
the DMA window configuration, and restore it at shutdown time. Make
sure that all assumptions we've made on the firmware's configuration
of DMA windows is correct.

thorpej | According to section 8.1.2.2 of the Tsunami/Typhoon hardware reference
manual (DS-0025A-TE), the SGMAP TLB is arranged as 168 locations of 4
consecutive quadwords. It seems that on some revisions of the Pchip,
SGMAP translation is not perfectly reliable unless we align the DMA
segments to the TLBs natural boundaries (observed on the API CS20).
N.B. the Titan (as observed on a Compaq DS25) does not seem to have this
problem, but we'll play it safe and run this way on both variants.
PR port-alpha/40604.

thorpej | Oops, pass the correct bus_dma_tag_t to the "hi" sgmap init function.

thorpej | - Don't bother issuing a warning if we program the WBASE / WSM register
to different values than the firmware.
- Reduce the differences in how we initialize the DMA tags vis a vis the
other Alpha implementations.
- Use Window 2 to provide a 1G @ 3G PCI SGMAP window on systems with more
than 1G of RAM, rather than falling back on the ISA DMA window which is
small and could get starved by PCI devices.
- Make sure we set TBASE to 0 for direct-mapped windows.

thorpej | Remove unnecessary #include <sys/malloc.h>

thorpej | The Tsunami / Typhoon chipsets have a static "monster window" for DMA
that allows for up to 32GB of RAM to be direct-mapped if the PCI device
can issue a 64-bit address (the monster window lives at 0x10000000000).
Enable this window and provide this to the PCI bus as a "dmat64".

tsutsui | Add support for AlphaStation DS15.
Ported from OpenBSD via PR port-alpha/48148 by nullnilaki.
Note support for the secondary PCI bus still needs more improvements.

matt | branches: 1.12.6; 1.12.10;
Do a minor cleanup of alpha (this will make applying pullups post branching
easier).
u_int{8,16,32,64}_t -> uint{*}_t
Change all old-style definitions to C89 prototypes.
Whitespace cleanup.
Constification in db_disasm.c

dsl | branches: 1.9.4;
Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

bouyer | Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
