G/C ARM32_NEW_VM_LAYOUT

Use a std.evarm to handle the normal EXEC_ELF32/EXEC_SCRIPT and ARM options
as well as include conf/std and std.arm

Add a std.evbarm to include std.arm and remove std.arm inclusion from std.*

Enable bounce buffers

branches: 1.15.44; 1.15.54;
Add an arm/conf/std.arm file which contains common arm options, initially
just options CPU_IN_CKSUM.

Include std.arm in all arm platform std files.

This should reenable the asm in_cksum code for all arm platforms.

Also remove the now unused in_cksum_arm.S.

branches: 1.14.46; 1.14.50; 1.14.56;
merge ktrace-lwp.

include "conf/std".

branches: 1.12.16;
Switch to using generic soft interrupts.

branches: 1.11.2;
Don't need ARM32_PMAP_NEW option any more.

Switch Integrator, IXM1200, and SMDK2800 to ARM32_PMAP_NEW. These
are the last of the ARM platforms to be converted.

Remove LINKENTRY and LOADADDRESS vars; it's all handled by the linker
script on evbarm platforms.

Split board-specific Makefile fragments into their own files.

Clean up evbarm interrupt support a little:
* Define an ARM_INTR_IMPL option, which specifies a header file
describing the interrupt implementation for the platform. Use
this instead of the list of EVBARM_BOARDTYPE checks.
* Make the s3c2xx0 interrupt dispatch code a bit more generic, and move
it to a generic location so that other platforms can use it.

This eliminates all uses of the EVBARM_BOARDTYPE stuff, so delete it.

Add a new option EVBARM_BOARDTYPE to differentiate between different
evbarm ports. Inline _splraise/_spllower/splx for i80321 and iq80310
for more performance.

branches: 1.5.8;
New interrupt framework for NetBSD/evbarm, and accompanying new
interrupt code for the IQ80310 board support package.

XXX The Integrator board support package still uses the old-style
arm32 interrupt code, so some compatibility hacks have been added
for it. When the Integrator uses new-style interrupts, those hacks
can go away.

branches: 1.4.2;
Don't need "options PROG32" anymore.

cleanup:
options SPACE TAB
makeoptions TAB
psuedo-device TAB
remove trailing whitespace
replace multiple spaces -> tabs
options "FOO" -> options FOO
options "FOO=bar" -> options FOO=bar
options "FOO=\"bar\"" -> options FOO="\"bar\""

branches: 1.2.2; 1.2.4;
Move board-specific config definitions into files.<board>, allowing
each board type to have its own device namespace.

Configuration for Integrator boards.
