The hardware can be set to limit the number of interrupts from 2 to 63
interrupts per ms.
To keep the compatibility with the TI documentation the sysctl take the
interval between the interrupts pulses: 16~500 us.

Summary:
This enables some features of the DIU, using a static configuration,
specified either via a 'edid' property on the 'display' FDT node, or a
'video-mode' environment variable (bootarg). 'video-mode' was chosen because it
matches u-boot's naming, so it can be set with:
setenv bootargs video-mode=${video-mode}
at the u-boot CLI.
Mouse cursor is not supported currently, as a hardware cursor is not supported
by framebuffer VT yet. Currently it only supports a 32bpp ARGB (actually BGRA)
format, and only a single composite plane, at up to 1280x1024.

Elantech trackpads are found in some laptops like the Asus UX31E. They
are "synaptics compatible" but use a slightly different protocol.
Elantech hardware support is not enabled by default and just like
Synaptic or TrackPoint devices it should be enabled by setting
tunable, in this case hw.psm.elantech_support, to non-zero value

1. macOS nor Linux have MAP_NOCORE nor MAP_NOSYNC. Define as 0.
2. macOS doesn't have SEEK_DATA nor SEEK_HOLE. Define as -1
so that lseek will return -1 (with errno set to EINVAL).
3. gcc correctly warns that error is assigned but not used in
image_copyout_region(). Fix by returning on the first error.
Not only is the header unportable, the encoding/decoding functions
are as well. Instead, duplicate the handful of small inlines we
need into a private header called endian.h.
Aside: an alternative approach is to move the encoding/decoding
functions to a separate system header. While the header is still
nonportable, such an approach would make it possible to re-use the
definitions by playing games with include paths. This may be the
preferred approach if more (build) utilities need this. This
change does not preclude that. In fact, it makes it easier.
Clear 'sc_calibrating' flag and stop calibration task when interface

(1) Print the default segment %ss before adresses relative to %bp.
This is too cluttered for me, but so is printing some other default
prefixes, and this is a reasonable reminder that %ss is quite
likely to be different from %ds in 16-bit mode.
db_disasm still handles prefixes poorly, by trying to discard
redundant ones. This loses information, and sometimes the result
is wrong or misleading.
Clean up nearby initializations and dead code.
(2) Fix decoding of operand and address size prefixes in 16-bit mode.
They reverse the default in all modes.

db_segsize().
Use db_segsize() to set the default operand/address size for
disassembling. Allow overriding this with the "alternate" display
format /I. The API of db_disasm() should be debooleanized to pass a
more general request (amd64 needs overrides to sizes of 16, 32, and
64, but this commit doesn't implement anything for amd64 since much
larger changes are needed to restore the amd64 disassmbler's support
for non-default sizes).
Fix db_print_loc_and_inst() to ask for the normal format and not the
alternate in normal operation.
This is most useful for vm86 mode, but also works for 16-bit protected
mode.
Use db_segsize() to avoid trying to print a garbage stack trace if %cs
is 16 bits. Print something like the stack trace termination message
for a trap boundary instead.
Document that the alternate format is now useful on i386.
early printfs and debugging of vm86 initialization and some other early
initialization in some cases.) Add an option debug.late_console (with
default 1=off) to move console and kdb initialization back where it was.
Do the same for amd64 although there is no vm86 there.
On my test system, debug.late_console=0 works for the syscons, sio and
uart console drivers on amd64 and i386, and for vt on i386 but not on
amd64.
The early printfs fixed by debug.late_console=0 are:
- on i386, the message about lost memory above 4G
- with -v in otherwise normal use, about 20 printfs for SMAP
- other debugging messages for memory sizing. Mostly under -v and
not printed in normal use.
Document in a comment how much earlier the initialization and early
printf()s can be. That is very early for the console. Not much more
than curthread is needed. kdb use obviously needs to be not so early,
since it needs IDT initialization and that is done relatively late
for convenience and historical reasons.

build can break when different source files create the same target
files (case-insensitivity speaking). This is the case for object
files compiled with -fpic and shared libraries. The former uses
an extension of ".So", and the latter an extension ".so". Rename
shared object files from *.So to *.pico to match what NetBSD does.
