Whitespace consistency.

everything else just <tab?

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.*

branches: 1.21.2; 1.21.12;
add missing KERNEL_BASE_EXT.

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: 1.19.46; 1.19.50; 1.19.56;
merge ktrace-lwp.

include "conf/std".

Don't need ARM32_PMAP_NEW option any more.

Adapt to ARM32_PMAP_NEW.

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: 1.11.2;
XSCALE_CCLKCFG should not be set in std.iq80310. Set IQ80310 to use
XSCALE_CCLKCFG=9 (733MHz) and TEAMASA_NPWR to use XSCALE_CCLKCFG=7 (600MHz)
as that's what the part on the board is rated for.

branches: 1.10.2;
Two changes for XScale:
1) Add defparam XSCALE_CCLKCFG to define a parameter for the
CCLKCFG register. Default it to '9' on the IQ80310.
2) Add a sleep call to the xscale CPU function vector (replacing
the nullop) which should drop the CPU into "idle" mode when
cpu_switch finds nothing on the run queues.

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: 1.7.2;
Add PCI_NETBSD_CONFIGURE.

Rework and fleshing out of Intel IQ80310 XScale eval board support.
More work to do -- this is a snapshot of work-in-progress.

Don't require the IQ80310 option. Made possible by files.<board>.

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

Define BOARDTYPE in the Makefile so that the target-specific
Makefile fragment (to be added shortly) can DTRT based on the
board we are building a kernel for.

branches: 1.2.4;
Add a NEWINTR option to reflect the new interrupt/spl being implemented in
evbarm.

more evbarm files (very incomplete).
