Whitespace consistency.

everything else just <tab?

branches: 1.5.36; 1.5.38;
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: 1.3.14; 1.3.24;
i80321-based systems use a virtual base of 0xc0000000 so specify
KERNEL_BASE_EXT.

branches: 1.2.6; 1.2.10; 1.2.18; 1.2.20;
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: 1.1.2; 1.1.6; 1.1.8; 1.1.30; 1.1.34; 1.1.40;
Add support for the Certance CP-3100.

"The Certance CP3100 product family provides high-end disk-to-disk-to-tape
(D2D2T) functionality for small-to-medium businesses."

To software, the unit is very similar to the IQ80321 and IQ31244 eval
boards from Intel. As such, we share almost all of their code.

Onboard hardware:
- IOP321 XScale CPU. Core clock is 600MHz.
- 256MB SDRAM (not sure if that's true for all)
- Four-port Intel i31244 SATA controller. One port is connected to the
internal disk. The remaining three are available on the back-panel.
- Dual GigE ports on the back panel, using an Intel i82546EB controller.
- Two Symbios Logic 53c1010 SCSI controllers, one in host mode the other
in target mode. Both SCSI busses are available on the back panel.
Note that NetBSD does not support SCSI target mode.
- 8MB of NOR Flash, containing a fairly vanilla Redboot together with
a minimal compressed Linux image.
- Some front-panel LEDS (not supported).
- Serial console.
