spi -- introduction to machine-independent SPI bus support and drivers SYNOPSIS
spi* at mainbus? Other attachments are machine-dependent and will depend on the bus topology of your system. See intro(4) for your system for more informa- tion. DESCRIPTION
NetBSD includes a machine dependent SPI (Serial Peripheral Interface) bus subsystem, and several different machine-independent SPI device drivers. Your system may support additional machine-dependent SPI devices. Consult your system's intro(4) for additional information. SPI is a 4-wire synchronous full-duplex serial bus. Some systems provide support for Microwire, which is Philips' name for a strict subset of SPI, with more rigidly defined signaling. Therefore, Microwire devices are also supported by the SPI framework. Note that when referencing SPI devices in a config(1) file, the 'slave' must be provided, as SPI lacks any way to automatically probe devices. HARDWARE
NetBSD includes the following machine-independent SPI drivers m25p STMicroelectronics M25P family of NOR flash devices. tm121temp Texas Instruments TMP121 temperature sensor. SEE ALSO
m25p(4), tm121temp(4) HISTORY
The machine-independent SPI framework was written by Garrett D'Amore for the Champaign-Urbana Community Wireless Network Project (CUWiN), and appeared in NetBSD 4.0. BSD

I noticed some strange looking parameters on some processes on one of our servers, and after a little playing around we deduced that ksh seemed to be adding a (somewhat random) extra parameter when calling a script without a hashbang in it.
