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.

Fix build by renaming the pinctrl driver

branches: 1.18.12;
Add ure(4) to kernel config files. Also add PHY drivers where necessary.

branches: 1.17.4;
clean up COMPAT_* options for native netbsd code:
- new series of files that are useful for saying "i want everything
since netbsd 1.4", etc.
- use the fact COMPAT_* options have future dependancies to remove
many redundant options.

removes about 3000 lines total across kernel configuration files.
tested about 30 random kernels in the changed list.

PR kern/51208
Add DISKLABEL_EI option (and also FFS_EI if missing), commented out except for
ALL on amd64 and i386.

branches: 1.15.2;
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.

branches: 1.12.2;
Add `pseudo-device ksyms' where `options DDB' is used, because
config(1)/config(5) can't handle module dependency correctly at this
moment.

(This is another proof that shared file definition (`file xxx.c a|b')
is a bad idea.)

Petri Laakso <petri.laakso@asd.fi>
- New audio driver
- Add new devices rtc and digfilt
- Use BOOT_ARGS if defined in kernel configuration

branches: 1.10.2;
Device midi attachment where the evil usbdevices.config is included.

Create an "options MODULAR_DEFAULT_AUTOLOAD" config option and add
it to all kernel configs that contain "options MODULAR". This
option turns on module autoloading by default (which is the current
default). This allows people who don't want module autoloading on
by default to disable it by simply removing/commentting this line.

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: 1.5.2;
Add COMPAT_NETBSD32 to more kernels (we have too many)

branches: 1.4.2;
iMX233/OLinuXino changes from Petri Laskso.
See http://mail-index.netbsd.org/port-arm/2013/10/07/msg002042.html

branches: 1.3.6;
Contribution from Petri Laakso:
- DMA driver stub code replaced with working code.
- Add support to multi block DMA in ssp driver.

branches: 1.2.2; 1.2.6;
Contribution from Petri Laakso: Initial support for SD card controller.
iMX233-OLinuXino can now boot and run from its own SD card.

Add initial support for Olimex iMX233 based OLinuXino boards.
