simplify compile-time default keyboard map generation

[emaste]

Summary

In rS296926 the -P <path> option was added to kbdcontrol, in order to simplify building compile-time default keymaps. Make kbdcontrol a build tool to use the new -P support.

[op]

Looks good to me, but not yet tested (I will at weekend.).

Btw, other architectures are not affected?
Or would not be better to move the generation of this file to the generic config rather then keeping them in arch specific files?

[op]

Tested with these settings:

• built SC kernel on VT kernel:

makeoptions KBDMUX_DFLT_KEYMAP="us.pc-ctrl"
makeoptions UKBD_DFLT_KEYMAP="us.pc-ctrl"
makeoptions ATKBD_DFLT_KEYMAP="us.pc-ctrl"

• built VT kernel on SC kernel:

makeoptions KBDMUX_DFLT_KEYMAP="us.ctrl"
makeoptions UKBD_DFLT_KEYMAP="us.ctrl"
makeoptions ATKBD_DFLT_KEYMAP="us.ctrl"

• built VT kernel on VT kernel:

makeoptions KBDMUX_DFLT_KEYMAP="us.ctrl"
makeoptions UKBD_DFLT_KEYMAP="us.ctrl"
makeoptions ATKBD_DFLT_KEYMAP="us.ctrl"

Btw, it would be nice to MFC this change to 10-STABLE too.

Yes, I intend to bring in an updated version of the kbdmux keymap change, and merge all of the kbdmap changes to stable/10 in a while.
