Add the beginnings of a GENERIC_V5 kernel that targets armv5 boards and
uses FDT.

In this first iteration some support is added for OLinuXino boards.

Thanks to Yuri Honegger for doing the vast majority of the work.

Adjust _all_ cinclude of *.local files

- Ensure always at end
- Use tab rather than spaces
- Add consistent comment
"Pull in optional local configuration - always at end"

The only functional change is that a local file which tried to
override an existing setting (eg with "no foo") would have failed
in some cases before, but now will work

Re-factor and overhaul the "mcp23s17gpio" driver as "mcpgpio", and
add support for 8-bit and I2C variants of the chip:
- MCP23008 / MCP23S08: 8-bit (I2C / SPI)
- MCP23017 / MCP23S17: 16-bit (I2C / SPI)
- MCP23018 / MCP23S18: 16-bit (I2C / SPI), open-drain outputs

The MCP23x17 and MCP23x18 are essentially identical, software-wise; we
merely report different GPIO pin capabilities (no push-pull output for
MCP23x18). Also, remove the tri-state capability that was previously
advertised by the old version of this driver; these chips have no way
to put the pin into a HI-Z mode.

All 3 I2C versions are supported, but the SPI front-end still only
supports the MCP23S17 for now (SPI autoconfiguration needs an overhaul).

mcp23s17gpio(4) remains present as a link to the new mcpgpio(4) man page.

XXX Still to-do: FDT integration, interrupt suppoort.

Support EARLYCONS and VERBOSE_INIT_ARM for Raspberry Pi Zero W, for
which mini UART should be used instead of PL011 UART.

branches: 1.93.2;
Add bigger console font for modern displays.

Add smscphy(4).

Separate devicetree .dts -> .dtb building from kernel builds. They are now
part of a separate set, "dtb.tgz", and only built when MKDTB=yes. This
defaults to yes for earmv[67]* and aarch64, and no everywhere else.

PMAP_DEBUG has been deleted on arm

branches: 1.89.4;
Add builtin WiFi and Bluetooth.

Remove the strip(4) - Starmode Radio IP - pseudo-device driver. It is
long since obsolete.

branches: 1.87.4;
Rename watchdog -> bcmpmwdog and sdhost to bcmsdhost

Add DTS for Raspberry Pi Compute Module IO board rev1

Provide generic start code that assumes the MMU is off and caches are
disabled as per the linux booting protocol for ARMv6 and ARMv7 boards.
u-boot image type should be changed to 'linux' for correct behaviour.

The new start code builds a minimal "bootstrap" L1PT with cached access
disabled and uses the same table for all processors. AP startup is
performed in less steps and more code is written in C.

The bootstrap tables and stack are placed into an (orphaned) section
"_init_memory" which is given to uvm when it is no longer used.

Various kernels have been converted to use this code and tested. Some
boards were provided by TNF. Thanks!

The GENERIC kernel now boots on boards using the TEGRA, SUNXI and EXYNOS
kernels. The GENERIC kernel will also work on RPI2 using u-boot.

Thanks to martin@ and aymeric@ for testing on parallella and nanosoc
respectively

Unreference IPF/PF from all the config files, and enable NPF instead when
wanted. This also fixes some inconsistencies I saw in several files (eg
IPF options while IPF was not compiled, IPF+PF enabled by default, etc).

RPI: remove commented-out pseudodevices

Remove a number of commented out pseudodevice lines that are
duplicative with GENERIC.common. Othewise, someone might think it
reasonable to uncomment or add them.

For now, a number of pseudodevices that are not in GENERIC.common
remain, pending comments on the larger-scale rototill.

Add bcm2835-rpi-zero-w.dts and bcm2837-rpi-3-b-plus.dts as appropriate

PR/53284 - Support RPI3B+,RPI0W,RPI2-1.2

Attach simplebus on pass 0

cpus: use fdt_add_bus

Allow nodes to attach child devices using the same sorting rules as used
by the simplebus driver.

branches: 1.78.2; 1.78.4;
FDTise RapberryPI support. Thanks for jmcneill for a lot of help with this.

The kernel image that the RPI firmware boots is now netbsd.img in the
kernel build directory.

XXX fdtbus_get_reg needs reworking

Disable USB_DEBUG by default

attach audio at audiobus (for pad)

Add bluetooth serial uart devices.

RPI3 on-board bluetooth controller works with the bthfive pseudo-device.

Add support for BCM2835 AUX UART.

enable sdhost driver (ok skrll@)

Add driver for the bcm2835 internal SD controller. On boards with SDIO
Wi-Fi, the internal SD controller is used for the SD card slot and the
Arasan SDHCI controller is used for SDIO.

wildcard speaker attachments, now that we can handle many of them.

remove VAUDIOSPEAKER for now, will be done differently.

Add a synthesized pc beeper and keyboard bell for platforms with an audio
device.

add commented out entry to attach Pi Face Real Time Clock

branches: 1.67.2;
undo unintended commit

Elide unused variable warnings (Felix Deichmann)

Fix commented out USB HC debug options. RPI doesn't have [eo]hci.

MI driver for the Microchip 3x0x series of SAR analog to digital converters.

Remove dmover(9) references

Use GENERIC.common

re-add ARM11_COMPAT_MMU, lost in the rpi2 shuffle

Initial RPI2 support - it doesn't work yet. The generic timer gets messed
up somehow.

This commit changes the KVA layout of the RPI.

branches: 1.59.2;
Move some options into std.rpi

add commented out entry for linksprite's RTC module

Device midi attachment where the evil usbdevices.config is included.

Introduce RPI_HWCURSOR and default to off. The existing code causes
problems with vchiq at the moment.

enable NFS root FS support in RPI

Re-enable bcmdmac by popular demand. It works now too.

Make emmc use of dma controller optional and disable the bcmdmac for now.

It doesn't work for me.

enable bcmdmac, now required by sdhc

add bcmdmac0, commented out until something uses it

Copy the list of PHYs from elsewhere.

XXX sys/dev/mii/miidevices.config anyone?

Systematize (and in many cases, fix) the comments on options COMPAT_NN.

There are quite a few configs that are missing some COMPAT_NN options
in ways that don't make sense; this should probably get cleaned up
too, but for the time being I've not added or removed anything.

Reorganize symbol table embedding. The existing option SYMTAB_SPACE is
replaced by the make option COPY_SYMTAB set to any value. The copy of
the symbol table is no longer put into a buffer in kern_ksyms.o, but a
small helper object. This object is build first with a dummy size, then
the kernel is linked to compute the real dimension of the symbol table
buffer. After that, the helper object is rebuild and the kernel linked
again.

Add "options COMPAT_70" to all kernel configuration files that
already had "options COMPAT_60".

branches: 1.46.2;
Add COMPAT_NETBSD32 to more kernels (we have too many)

"internally consistency checks" -> "internal consistency checks"

add Microchip MCP23S17 GPIO driver
(via SPI interface)

branches: 1.42.2;
More symbols

Switch to dwctwo(4) from dotg(4) for the RaspberryPi port. This brings
DMA support and (initial) isoc transfer support.

Remove URTWN_DOTG_WORKAROUND as dwctwo doesn't appear to need it.

bump symtab space

Bump symtab space.

Fix stale comment

Enable PUFFS

G/C PFIL_HOOKS from the kernel configs.

branches: 1.35.2;
Make this like all other INSTALL files. Override RAMDISKNAME to sshramdisk

Add missing filesystems in the filesystem list but comment them out.
Add missing KGDB options needed for KGDB working

Enable putter. Shoot me now.

Enable VCONS_DRAW_INTR speeding up the graphic console of the RPi
significantly!

enable vchiq, add vcaudio and audio drivers

add drvctl

Disable vchiq for now.

add vchiq0 at obio?

Under FAST_IPSEC, IPSEC_ESP is mandatory; GC it.

Retire OSI network stack. OK core@

Add PCVT compat (for X console switching) and SYSCONS for some more
ioctls.

add bcmrng

Change the root device to '?' instead of 'ld0a'.
This was overriding the root=device passed in on the kernel command line.

Bump SYMTAB_SPACE

enable framebuffer console driver

Enable COMPAT_60

Add ukphy

Add/enable USB

pull in RPI.local if it exists

add genfb, disabled for now

that already had commented out "#options COMPAT_50".

Add a bunch of pseudodevices and LOCKDEBUG. All commented out.

branches: 1.8.2;
Add PUFFS, putter and fss.

When we do get a working and stable USB HCD,
we'll want to use usbdevices.config.

Bump up SYMTAB_SPACE

Better/different/consistent wscons colours.

First pass at a VC mailbox driver.

Ensure all WSDISPLAY_COMPAT_USL entries have same comment

What was MEMSIZE is now determined automatically. Remove MEMSIZE.

branches: 1.1.2;
Initial commit of support for the RaspberryPI (www.raspberrypi.org)

This is enough for serial console via the gpio header pins and to get to
multiuser.

A huge thank you to Matt Thomas for all his help.
