#NO_UNIVERSE. Many of these config files are important examples, but
add little to no regresive value to the intended purpose of
UNIVERSE. We now build over 120 kernels during universe. There's
really little to no value to this over building say 60 or even 30 of
them (either is still a way too big number). This is especially true
for kernels that are nothing more than including a common base and
adding a static DTB file. Start by pruning 1/3 of the arm kernels that
add little regresion value.
enabled. Also switch IMX6 to use SCHED_ULE.
The now-unreferenced WANDBOARD.common config will be deleted after giving
folks who may be including it a heads-up to switch to IMX6.
Support covers device drivers for:
- Interrupt Combiner
- gpio/pad, External Interrupts Controller (pad)
- I2C Interface
- Chrome Embedded Controller
- Chrome Keyboard
Also:
- Use new gpio dev class in EHCI driver
- Expand device tree information
The ADC has a 12bit resolution and its raw output can be read via sysctl(8)
interface.
The driver allows the setup of ADC clock, samples average and open delay
(the number of clock cycles to wait before start the conversion).
The TSC_ADC module is set in the general purpose mode (no touchscreen
support).
Tested on Beaglebone-black.
Written based on AM335x TRM.

never actually ran on these chips (other than using SA1 support in an
emulator to do the early porting to FreeBSD long long ago). The clutter
and complexity of some of this code keeps getting in the way of other
maintenance, so it's time to go.
Quartz is a tiny module utilized Freescale VF6xx
system-on-chip and development kit produced by
Device Solutions.
Quartz is available in a form of LGA (38x38x2mm)
or as a module with high-density connectors.

WANDBOARD.common config, but with the freescale-specific optons and devices
all together at the bottom now. In addition to reformatting and shuffling
lines around, two new options are added because they're now known to work,
VFP and FREEBSD_BOOT_LOADER.
This config does not include any static DTB, it requires that u-boot
provide a DTB (or a custom kernel config can compile one in).
This will supercede all the existing WANDBOARD* configs, but those will
be left around for a while to help people transition their customized
configs to include this new one instead.
Add gpioled(4) to BEAGLEBONE kernel and add the description of the four
on-board leds of beaglebone-black to its DTS file.

This was an optimization used only by a few xscale platforms. Part of
the optimization was to create a direct map for all physical pages, and
that resulted in making multiple mappings of pages in a way that bypassed
the logic in pmap.c to handle VIVT cache aliasing. It also just generally
made the code more complex and hard to maintain for all SoCs.

in effect due to r250753. That is sufficient for all SoCs with a 32 byte
cache line size. Systems with 64 byte cache lines will need the option;
that will be done in a separate commit.
Thanks to loos@ for pointing out r250753.
Make comments match parameters
Add options for early printf so we get regression build testing on it.
Add preview of options for FDT support coming soon (I hope)
this to the cache line size is required to avoid data corruption on armv4
and armv5, and improves performance on armv6, in both cases by avoiding
partial cacheline flushes for USB IO.
