We need to special case ciphy to ask for RGMII interface at 2.5V for nfe.
This makes Cicada/Vitesse PHYs attached to nfe work.
Many thanks to Bill Paul for diagnosing the problem and suggesting a solution.

COMPAT_NETBSD32. They haven't worked for 5 years.
Silently agreed by the tech-kern readers.
XXX sparc64 MD glue still lacking.
XXX The FPU registers on i386 are not dumped correctly, according to my
XXX tests. It shouldn't be much work for someone who has the slightest
XXX idea of how that stuff is supposed to be laid out on i386.
FROMBCD()/TOBCD() macros into wrappers around it, resulting in both
smaller code footprint and elimination of possible issues due to
multiple evaluation of macro arguments.
Suggested by Simon Burge and Anders Gavare on tech-kern.
moving system call functionality from trap.c to new syscall.c
Split out userret from trap.c to <machine/userret.h> and use
mi_userret().
This gets approx 20% speed improvement (45us to 36us) with lmbench's
"lat_syscall null" benchmark(!).
The tadpole microcontroller sets an additional bit in frame headers from
an external mouse which caused our driver to discard the frame - now we
just ignore the bit.
the TOY register, which is presumed to be seconds since Jan. 1 2000.
For now I'm assuming the trim divider is 32K, which makes 1 tick per sec.
This is true for the DBAU1550 board at least. Other boards might need to
initialize a reasonable trim counter and establish the 32KHz oscillator.
In any case, this code is *no worse* on older systems than what was there
before.
1) create new pnpbus psuedo bus. This is a bus layer that reads the PNP
tree from the residual data and allows attachment of devices with the
information given therein. Based loosely on i386/pnpbios.
2) Delete obio bus, as with the pnp bus we no longer need it.
3) Create a number of functions that gather the information needed to set
up the machine from the residual data, rather than hardcoding it in.
4) Create a quirk table for machines that are bizzare enough that the
residual information is not sufficient. (such as the 6015)
5) Using the data gathering routines and the quirk table, delete struct
platform completely from the architecture. Prep is now almost completely
dynamic in figuring out the machine it is running on and setting things
up properly.
6) Add a wdc_pnpbus driver which attaches the wdc controller found on
some 7248's and the 6015. This replaces the now-defunct wdc_obio.
7) delete all the mot_* and ibm_* files, and replace them with a single
ibm_machdep.c which only contains the quirk functions for the 6015 and
the 6050.
8) Modify GENERIC to work with all this stuff.
Linux kernel-version as on i386 and ppc (currently 2.4.18), and a date
in Feb 2002.
On all other NetBSD platforms we return a Linux-kernel version of
2.0.38 and a date sometime in 2000, which (AFAIK) predates the
existence of amd64, and therefore predates Linux support for amd64.
To me, it makes much more sense to return the same Linux-kernel-version
and date for both 32-bit x86 and 64-bit x86.
Empirically (and not least), this change also allows SuSE 10 amd64
binaries to run under our Linux amd64 binary emulation (both static
and dynamic-linked, given suitable setup) , which they didn't when we
reported a Linux/x86_64 kernel version of 2.0.38.
I had duplicated them. Improve the macros' names. Simplify their
implementation.
A brief description of each macro is below.
BIT(n): Return a bitmask with bit m set, where the least
significant bit is bit 0.
BITS(m, n): Return a bitmask with bits m through n, inclusive,
set. It does not matter whether m>n or m<=n.
The least significant bit is bit 0.
A "bitfield" is a span of consecutive bits defined by a
bitmask, where 1s select the bits in the bitfield. SHIFTIN,
SHIFTOUT, and SHIFTOUT_MASK help read and write bitfields
from device registers.
SHIFTIN(v, mask): Left-shift bits `v' into the bitfield
defined by `mask', and return them. No
side-effects.
SHIFTOUT(v, mask): Extract and return the bitfield selected
by `mask' from `v', right-shifting the
bits so that the rightmost selected bit
is at bit 0. No side-effects.
SHIFTOUT_MASK(mask): Right-shift the bits in `mask' so that
the rightmost non-zero bit is at bit
0. This is useful for finding the
greatest unsigned value that a bitfield
can hold. No side-effects. Note that
SHIFTOUT_MASK(m) = SHIFTOUT(m, m).

cc_microtime with a MD function that isn't affected by erratic "clock
interrupts" and instead takes more advantage of time information
provided by the hypervisor. Fixes, most importantly, a case where the
clock as seen by userland would sometimes bounce back and forth by up to
1<<31 us (~35 min).
