`expansion layout [connector]`	Draw the board's physical connector map with live free, releasable, claimed, fixed, power, ground, and NC markers.
`expansion scan`	List expansion resources and probe-capable drivers.
`expansion drivers`	List compiled expansion drivers.
`expansion devices`	List manually attached expansion devices.
`expansion bus create i2c <name> port=<i2c0\	i2c1> sda=<gpio> scl=<gpio> [speed=<hz>]`	Define a runtime I2C bus on an unused controller and approved expansion pins.
`expansion bus create onewire <name> pin=<gpio>`	Define a runtime named 1-Wire bus on an approved expansion pin.
`expansion bus create ps2 <name> clock=<gpio> data=<gpio>`	Define an exclusive PS/2 bus on two approved expansion pins.
`expansion bus create spi <name> host=<spi2\	spi3> sclk=<gpio> mosi=<gpio> [miso=<gpio\	none>] cs=<gpio> [cs=<gpio> ...] [max=<bytes>]`	Define a runtime-routed SPI bus on a board-approved host and expansion pins.
`expansion bus create uart <name> port=<uart1\	uart2> tx=<gpio> rx=<gpio> [baud=<rate>]`	Define a lazy runtime UART on an unused controller and approved expansion pins.
`expansion bus attach <name>`	Attach a named detachable bus and reserve its endpoint and signal pins.
`expansion bus detach <name>`	Detach an idle named bus, preserving its descriptor while releasing its endpoint and signal pins.
`expansion bus remove <name>`	Remove an idle runtime bus and release its signal pins.
`expansion attach <driver> <name> <resource...>`	Attach a compiled expansion driver or manual resource profile.
`expansion detach <name>`	Detach an active expansion device and release its resource claims.
